How to treat an ear mite in a dog

How to treat a dog with ear mites?

For treatment, local agents are used. Currently, ear drops containing acaricidal substances are actively used. Often, such medicines also contain antibiotics, anti-inflammatory drugs. Ear drops often contain corticosteroids to relieve itching in your dog. But it is necessary to prescribe such medications only if it is established that the pathology is caused by ear or itchy mites. with demodicosis, steroids are contraindicated.

Affected animals and animals that have been in contact are treated with insecticides (flea drops, sprays), repeated after 2 weeks. Ivermectin at a dose of 200-400 mcg / kg (0.2-0.4 mg / kg) has a therapeutic effect in canine otodectosis.

  • an antiseptic solution or a special agent to liquefy the ear plug is introduced into the ear canal;
  • if perforation of the tympanic membrane is noted, then it is allowed to use exclusively saline solution;
  • massage the base of the ear for better separation of pathological contents;
  • clean the outer ear with cotton swabs;
  • the drug is introduced;
  • ear cleaning is best repeated every 2-3 days;
  • acaricidal preparations are applied at least twice with an interval of 10-14 days.

Double treatment of the ear canal is necessary to destroy the second generation of parasites. The fact is that drugs do not affect the eggs of ticks, and if you do not repeat the treatment after 10-14 days, then their larvae will reach sexual maturity and lay eggs again. At the same time, it is often noted that such larvae develop resistance to the active substance, which complicates therapy.

Amitraz, produced in the form of a 10-15% oil solution, has a good efficacy in the treatment of ear mites. It is buried in the ear canal after it has been cleaned. Cypermethrin is also used. The main thing in the treatment is two-fold processing and preliminary removal of pathological contents from the ear canal.

In some cases, additional therapy may be required. So, ear scabies is often complicated by bacterial otitis media. In this case, the dog needs to be prescribed antibiotics. it is good to do Novocaine blockade of the auricle. Novocaine in the form of a 0.25-0.5% solution is injected in a mixture with antibiotics (penicillin, streptomycin) subcutaneously into the base of the ear. Alternatively, broad Spectra antibiotics can be administered with feed or intramuscularly. In some cases, a surgical operation may be required. in case of suspected rupture of the membrane and complications in the brain.

If you are unsure of how to treat an ear mite in dogs, it is best to contact your veterinarian. It is almost impossible to cure an ear mite in a dog with folk remedies. Washing with decoctions of chamomile and celandine has no effect, the use of celandine juice leads to severe burns in the ear, but does not help from ticks. The addition of sulfur powder to the ear canal is also not highly effective.

Clinical presentation and diagnosis of the disease

Signs of an ear mite in dogs depend on the severity of the pathological process. In most cases, otitis externa develops. The main symptom of this pathology is head shaking and constant scratching of the ear with the limbs. Due to severe itching, dogs can rub their ears against various objects and injure their hind legs. In many ways, the severity of otitis media is determined by trauma to the skin with claws:

  • auricle hematoma;
  • suppuration of scratching;
  • development of a bacterial infection.

When examining the auricle in dogs, exudate is found. At the onset of the disease, the discharge has a brown tint of a liquid consistency. With a complication of the pathology, a purulent separable or ichorous exudate appears. This is a pathognomonic sign indicating the severity of the process.

An accumulation of thick dark brown exudate is noted in the auditory canal. By palpation, pain is established, at the base of the shell there may be edema, less often. a hematoma. Otodectosis is usually accompanied by hearing loss, more often it worsens, less often (about a ruptured eardrum) it may be completely absent. Very rarely, ear mites cause skin lesions elsewhere in the body.

To confirm the diagnosis, it is necessary to detect ticks. To do this, it is enough to place the pathological material (earwax, crusts) on dark paper and examine it under a magnifying glass. Even at low magnification, ticks are visible as white moving dots. Identification of parasites (in order to accurately identify the pathogen, since otodectos, sarcoptic mites can be detected) is carried out under an average microscope magnification. Microscopy is necessary to exclude other inflammatory ear diseases caused by bacteria, lice, fleas, allergens.

Causes of ear scabies in dogs

The disease is caused by microscopic mites that affect the inner surface of the dog’s auricle. The main causative agent of the disease is mites of the genus Otodectes. Other parasites are less commonly found in dogs, although otitis media can also lead to:

  • Sarcoptes;
  • Demodex;
  • Helioptes.

But these mites are not typical parasites of the auricle. they are usually found on the skin or in its thickness on the body of the animal. Only otodktos. ticks that feed on blood, lymph and material in the ear canal are responsible in 50% of cases for the development of otitis media in dogs.

Mites irritate the earwax glands and cause dark brown crusts made up of excess sulfur, epidermal scales, and inflammatory exudate. These signs are most likely due to hypersensitivity, so in some cases, ticks can be difficult to identify with cytological examination of the contents of the ears. Ear mites often leave the inflamed ear canal and move to other areas.

These mites are usually localized in the ear canal, but other parasitic sites are also possible:

  • head;
  • neck;
  • croup;
  • tail root.

Parasitic mites have an oval body, up to 0.4 mm in diameter. Four pairs of limbs, they are not divided into segments. The color of the body is brownish. Apodems are attached to the first two pairs of legs.

Modern research shows the presence of this mite in many adult dogs. This is due to the fact that with prolonged weak contact with the pathogen and stable immunity, it is possible to maintain a small population of ticks. The disease does not manifest itself clinically until a deterioration in health occurs. Pathological action is determined by mechanical tissue damage, allergic irritation, secondary infection.

The eggs of these mites have a sticky surface, which allows them to adhere to the skin of the auricle. The larva matures in 4-5 days, after which the larva of the first stage emerges from the egg, which has 3 pairs of limbs. The first molt occurs within 24 hours and a second stage larva is formed, which has 4 pairs of limbs. Before turning into a sexually mature individual, it is required to go through 2 more stages with intervals between transformations of 3-7 days.

Throughout the entire period of development, both larvae and adults are actively feeding. Sex differences appear in ticks already at the 3rd larval stage. And at this stage, females can already reproduce, and males reach sexual maturity only in adulthood.

Treatment and prevention of ear mites in dogs

An ear mite in dogs causes a severe lesion, accompanied by otitis media (external, middle), less often the inner ear and the lining of the brain are involved. The disease is caused by ticks of the genus Otodectes. It is a microscopic mite that feeds on the epithelium and lymph of the host’s tissues. In sick dogs, purulent exudate is secreted, the inner surface of the ear is covered with crusts. Pets are constantly combing their heads, causing additional severe injuries. For treatment, it is necessary to use drugs against parasitic mites. ivermectin, cypermethrin, which is best used topically. It is important to remove dirt from the ear beforehand. The processing procedure is repeated twice with an interval of 7-10 days.

Preventive actions

As with the prevention of any other infectious disease, dog owners need to prevent their pet from coming into contact with the source of infection. Transmission of the pathogen usually occurs from sick animals, less often through various care items. As noted by studies, puppies are most often infected from their mother, who can be a latent carrier of parasites.

You can prevent infection by isolating your animal. If the dog does not contact others, then infection may not occur, but it should be understood that not only dogs can act as source of ticks. cats are most susceptible to otodectosis. You can also get infected from other types of animals.

Isolation is an effective prevention method, but it does not completely protect your pet. Infection is still possible, including through care items. Therefore, you should regularly inspect the animal, and if brown content is found in the ears, immediately treat it with antiparasitic agents.

  • sick animals;
  • pets who have been in contact with them.

For treatment, the drugs prescribed in the section on treatment are used. ivermectin, cypermethrin. At an early stage, treatment of otodectosis is not difficult and is carried out at home.

The greatest danger of ear scabies is to puppies. In adults, the disease is less common. This is due to the weakness of the immune system of the young. Therefore, it is important to maintain strong immunity of the animal, which consists of proper nutrition, quality care, timely diagnosis and treatment of other diseases.

Owners need to protect their pets from stray and wild animals.

What is this tick?

The Otodectes cynotis mite lives in the external auditory canal of many carnivores (dogs, cats, ferrets, polar foxes). It feeds on blood, lymph, earwax and skin particles, constantly releasing, of course, its waste products.

A dog can become infected at any time of the year. This is due to the fact that ear mites live in a closed space (auricle), where suitable conditions for their life and development are constantly maintained. But the number of parasites can vary and will depend on the physiological state of the dog. That is, the younger the dog (still weak immunity) or the weaker the health of the animal, the higher the risks of developing otodectosis.

Ear mite affects animals of various ages, but young animals from 1.5 to 6 months are more affected.

Drops in the ears “Anandin”

After cleaning the ears, 3-5 drops of the drug (depending on the size of the dog) are instilled into each ear, even if only one is affected. Drops are applied once a day for 4-7 days until the discharge disappears.

Ear mite in dogs: treatment, drugs, drops to remove the tick

When the dog begins to scratch the ear intensively, shakes its head, tilts its head to one side, black crusts are found in the ear. the owner may suspect that his pet suffers from otodectosis (ear mite). This disease is caused by a microscopic mite parasitizing in the auricle. However, such symptoms can be present with other ear pathologies, so you should definitely show the dog to a veterinarian.

Drops from the ear mite “Amitrazine”

1-2 ml of the medicine is instilled into each ear. Repeated injections are made 1 time in 3 days until complete recovery.

How does the infection occur, how is the ear mite transmitted?

An ear mite is transmitted when a healthy dog ​​comes into contact with an infected dog. Cases of infection through individual things (shoes, etc.) are recorded, but more often this is true for small dogs and animals with weakened immunity. In young puppies, the source of infection is often the mother.

Ivermec gel

A strip of gel 0.5-2 cm is applied deep into the ear canal (in both ears) and massaged thoroughly. Processing is carried out twice with a break of 5-7 days.


An ear mite causes an infectious disease in a dog, which, as a rule, is chronic. In the habitats of the ear mite, there are:

  • redness,
  • swelling,
  • during the inflammation, a characteristic fluid is released, which, together with dead skin particles, earwax and tick waste products, forms black-brown crusts in the dog’s auricle,
  • in case of complication by secondary microflora, the process switches to secondary and internal care and then to the meninges (it is rare).

When parasitizing a dog with an ear mite, the owner may notice the following symptoms:

  • persistent itching: the dog tries to scratch the ears on objects or scratches them intensively with its claws (often bloody),
  • the position of the dog’s head becomes unnatural: the head is lowered or tilted towards the affected ear,
  • with an advanced form of the disease, pus forms in the auricle, which sticks together the wool on the lower edge of the ear,
  • in the case of the transition of inflammation to the meninges, nervous disorders develop, during which the dog dies.

Does the disease depend on the season

An ear mite can “cling” to a pet at any time of the year. unlike ixodid ticks, this parasite is active in winter as well. Their reproduction does not depend on air temperature, daylight hours and other conditions. Since they live in the ear canal, they do not have a rest period. This means that the owner must be on his guard even in severe frost, not allowing contact between his pet and stranger dogs.


Treatment for ear mites in dogs is based on the mandatory use of medications. Without the use of drugs, getting rid of the parasite will not work. The owner should be patient, as the process can take a long time. Since insect larvae persist in the environment, careful treatment of the room in which the dog lives, as well as the items of care for it, will be required to prevent re-infection.

Drug therapy

Drugs for the treatment of otodectosis in dogs differ in composition, manufacturer, form of release, price and other parameters. It is not recommended to buy a product at random: before removing the parasite, you need to consult a specialist.

The most popular drugs for ear mites in dogs are presented in the table.

Ear mites in dogs

Ear mites in dogs and other animals lead to the development of otodectosis disease. If you skip the onset of infection, the process becomes chronic and threatening, up to the death of the animal. To avoid the sad consequences, the owner needs to know the features of the tick infestation of the pet, the symptoms of the disease and the main directions of treatment.

What is an ear mite

What does a parasite look like? This is a very small insect, not reaching one millimeter, with a grayish-white translucent body, which has a gnawing mouth apparatus. He gnaws at the skin and makes moves under it, laying eggs in them.

The wounds become inflamed and fester. The larvae, feeding on suppuration products and lymphatic fluid, reach sexual maturity after 3-4 weeks, and then also lay eggs. In a short period of time, an ear mite can damage not only the skin of the dog’s ear, but also the eardrum, and penetrate further into the inner ear and brain.

The disease develops imperceptibly. when the animal begins to show signs of the presence of a tick, then, as a rule, a significant part of the ear is affected. In addition, it was noticed that the activity of the insect is subject to some cyclicality: the period of activity and vivid symptoms are replaced by more or less calm intervals. Perhaps this is due to the cyclical development of the parasite. When the pathology takes on threatening forms, there are no rest periods.

Traditional methods of treatment

Sometimes dog owners use folk remedies to get rid of the ear mite. Compositions based on kerosene and vegetable oil, oil and iodine, strong tea are popular. Sometimes vegetable oil is mixed with garlic juice. This approach to the therapy of otodectosis cannot be considered correct. Firstly, such compositions, if they can help, then only at the very early stage of the development of the disease, when the number of ticks is low.

Secondly, garlic juice, kerosene, iodine have a strong irritating effect on the skin of the animal. The application of these components to the damaged lining can lead to burns, and if they penetrate into the inner ear, lead to complete deafness.

Can a person get an ear mite from a dog?

Can. Although rare, cases of the development of otodectosis in humans are also found. The symptoms of the disease are the same: itching, inflammation, swelling of the ear canal, accumulation of waste products of insects.

Ear mites in dogs. otodectosis

Ear mites, or scientifically otodectosis, often affects our dogs and gives them a lot of unpleasant sensations. The people call this ailment ear scabies, and not without reason, because the parasite provokes the disease, which is localized in the auricles of the animal, forcing it to behave unusually. What kind of disease is it, how can it be recognized and, most importantly, get rid of it in time?

Treating ear mites in dogs

There are many reasons why it is not worthwhile, without experience, to engage in independent treatment of a four-legged friend:

  • Only a specialist after a comprehensive diagnosis can confirm that the pet has otodectosis.
  • When choosing a drug, the doctor takes into account the individual characteristics of the dog (breed, tendency to allergic manifestations, neglect of the disease) and prescribes the optimal remedy.
  • An experienced veterinarian will be able to calculate the required dosage, as well as the duration of the course.

All anti-parasite agents can cause allergies, as they contain special components that are poisonous to insects. Therefore, it is necessary to constantly monitor the animal and, in case of any symptoms, go to the clinic. the doctor will prescribe another drug.

Before applying external agents, it is imperative to clean the auricles from accumulated sulfur, leaked exudate, and crusts. To do this, you can wrap a piece of gauze or bandage around your index finger and wipe the inside of the sink. The bandage can be moistened with a solution of boric acid, furacilin or hydrogen peroxide. In the latter case, it is necessary not to allow the drug to drip into the ear.

The procedure can be supplemented by applying vegetable oil to the baked crusts, or by treating them with freshly brewed tea leaves. To do this, it is convenient to use cotton swabs and change them as often as possible.

For the same purposes, you can purchase special lotions at the veterinary pharmacy, for example, “Epi-Otik” or “Otodin”, which will facilitate the removal of crusts, eliminate an unpleasant odor, and they also have a pronounced antipruritic effect. They can also be used as a prophylactic agent.

It doesn’t matter if one auricle is damaged or both are affected. two ears are always subjected to the procedure. You cannot use the same material to clean both ears. when switching to the second ear, you need to take a clean stick or put a new bandage on your finger. Such treatment is an excellent preventive measure that protects against the further spread of parasites.

Drops are usually given to treat ear mites in dogs. It is necessary to instill in both ears, strictly taking into account the prescribed dosage.

Among the well-known ear drops from otodectosis in dogs, the following can be noted:

  • “Amitrizan Plus”;
  • Otovedin;
  • “Surolan”;
  • Otibiovin;
  • “Tsipam”;
  • “Aurikan”;
  • “Leopard”.

For external treatment, ointments may be prescribed by a veterinarian:

  • “Oridermil”;
  • “Amidel-gel”;
  • “Sulfuric ointment”;
  • “Colloidal sulfur”;
  • “Aversectin ointment”;
  • “Vishnevsky balsamic liniment”.

The ointment must be warmed to room temperature, applied to the affected area with light massaging movements so that the medicine penetrates into the deeper layers of the epidermis.

You should know that such remedies eliminate the adults of the parasite. Therefore, it is necessary to repeat the treatment after a week and a half after the first course. Do not forget about possible allergic manifestations, and if, after using the product, the pet has skin hyperemia, itching, skin rash, then you need to consult a doctor.

If, after the completed therapeutic course, the subcutaneous tick reappears, it means that we are talking about incorrect or insufficient treatment, or the dog has low immunity.

Development of otodectosis in dogs

Penetrating on the body of an animal, the tick strives to get into its favorite habitat. the ears. It is here that the food for this parasite is found. blood, earwax. Biting the delicate skin, the tick leaves behind ulcerated, festering areas, from which the fur subsequently falls out.

The saliva of an insect thins the blood, making it easier to saturate it. In this case, substances contained in the parasite’s saliva cause allergic reactions in the animal. And the main symptom of allergy in this case becomes unbearable itching.

The surfaces affected by the mite are compacted and covered with dried crusts. I must say that the disease looks unpleasant and, having seen formations in the ears of a pet, the owners most often think that his ears are simply dirty. In fact, this is far from the case.

When a dog scratches its ears during otodectosis, it inflicts wounds on the affected skin, and this causes the development of an inflammatory process. a secondary infection that often accompanies the disease. Itching in the ears can also be caused by other reasons, not always of a parasitic nature, but inflammation most often signals an infection with an ear mite.

Consequences of advanced otodectosis

A tick bite is not only unpleasant sensations of the dog, but also a possible cause of various kinds of complications. If the pet is not treated, then this can lead to the following consequences:

  • festering of the resulting wounds;
  • the development of an inflammatory process in the ear. otitis media;
  • damage and further destruction of the tympanic membrane;
  • decreased or complete hearing loss;
  • inflammation of the membranes of the brain and spinal cord. meningitis.

Statistics indicate that complications develop in one out of ten cases of otodectosis. Naturally, this is not a reason to panic, but a warning. a sick animal must be cured in a timely manner.

Symptoms of Otodectosis in Dogs

As already noted, tick saliva is an allergen for an animal, but not only it, but all other products of its vital activity are toxic. Getting on the skin and in its inner layers, they lead to the appearance of microscopic tears, provoking itching in the dog. The pet is constantly scratching and shaking its ears. Scratches and wounds appear in the auricles and on the outside of the ear. Earwax mixes with lymph, mite feces and forms brown crusts.

In addition, a number of symptoms are added:

  • the dog begins to eat poorly, sometimes refuses food altogether;
  • the pet does not sit still, behaves restlessly;
  • in case of severe damage, the dog can constantly tilt its head towards the affected ear.

To identify the cause of this behavior, that is, the parasite itself, an examination of the ear canal is necessary. Using a cotton swab, you need to clean the auricle and place the contents on a dark sheet of paper. The seized sample must be delivered to the veterinary clinic.

In a clinic, the resulting material is examined under a microscope. If it really is a tick, then you can see the moving tiny gray-white specks.

But if you cannot see the parasites, then this does not guarantee their absence. In the initial stage of the development of the disease, this usually happens. In this case, only a veterinarian can identify the disease.

Ear mite preventive measures

Since the parasite is transmitted from an infected animal, you should protect your pet from communicating with yard and stray dogs. This is the main preventive measure.

Regular examination of the dog for parasites is required, and do not forget to pay attention to the ears. This is especially important for pets with hidden auricles, since it is not always possible to detect a tick or inflammation in them in time.

If brownish sulfur begins to form, it means that the animal has become infected with an ear mite.

By regularly cleaning the auricles, you can remove the parasites that have just entered the ear, preventing the development of the disease. And, in addition, such hygiene will not allow the spread of infection.

Do not neglect the use of special insecticidal agents against parasites. drops, sprays, shampoos. Dogs need treatment prior to seasonal parasitic insects. You need to choose the funds carefully, especially if the pet has a tendency to allergies.

Like most diseases, otodectosis is very easily cured at the very beginning of development. At this stage, regular cleaning of the ears and the use of special drops will help to relieve the pet of ailment.

If it was not possible to identify the subcutaneous tick, and it caused significant damage to the dog, then not only otodectosis will have to be treated, but also the secondary infection that has joined. This will take more effort and time.

How does the disease arise and progress?

The main cause of infection with an ear scabies mite in a dog occurs through direct contact of sick animals with healthy

For example, on a walk, when communicating with stray animals, which, most often, become the source of the spread of the disease.

In addition, given that the parasite retains viability, for some time, outside the body of the animal, infection can be carried out through care items, hands, shoes of the owner, and other objects with which the dog comes into contact.

Mites live on the surface of the skin and feed on the epidermis (cells in the top layer of the skin). By damaging the skin, ear parasites cause chemical and mechanical irritation of the skin receptors. Severe itching occurs. The damaged area becomes inflamed, accompanied by redness, swelling, and inflammatory effusion.

Inflammatory exudate, mite excrement, dead skin cells, dust and earwax mix and dry to form brown scabs on the skin surface. Dried crusts, accumulate in the lumen of the external auditory canal, contributing to blockage, and the accumulation of inflammatory effusion in the ear canal.

In such cases, perforation of the tympanic membrane may occur, while the inflammatory process continues, in continuation, to the middle, and then, to the inner ear of the dog.

In the most advanced cases, if untreated, the inflammation spreads to the lining of the brain, meningitis develops, and the animal dies.

Ear mites in dogs (otodectosis): effective treatment

Otodectosis or ear scabies. chronic invasive disease caused by microscopic scabies skin mites.

In addition to dogs, the ear mite most often affects cats, ferrets and fur-bearing animals (arctic fox, sable, mink, fox, rabbits). A person who has carnivore scabies does not get infected.

Correct treatment

In the initial stage, when there are no symptoms of otitis media, the disease is easily treated. For treatment, it is enough to destroy the ear mite in the dog. For this purpose, insecticidal preparations are prescribed, made on the basis of the same substances that are used in the treatment of skin scabies in animals.

The drugs used to effectively treat ear mites can be topical, in the form of drops, sprays and ointments, or general, in the form of injections. The drops and sprays used for the treatment of otodectosis, as the main active ingredient, include one of the insecticidal acaricidal agents.

In addition, the composition of drugs may include anti-inflammatory, bactericidal, antiallergic and antiseptic drugs.

Clusters in the ears

Accumulation on the inner side of the auricle and in the lumen of the external auditory canal of crusts, dirty brown.

In cases of complications, symptoms appear:

  • Otitis media (inflammation in the middle ear). discharge from the ear, fever, unpleasant odor from the auricle
  • Labyrinthitis (inflammation of the inner ear). disorders in coordination of movements are added to the symptoms of otitis media, the dog keeps his head turned 90-120 degrees;
  • Meningitis. whirligig, seizures and convulsions.


If you suspect a disease of otodectosis, you need to contact a veterinary clinic, after examination and microscopic examination of scabs for the presence of a parasite, the doctor will prescribe the necessary drugs and draw up a treatment regimen.

Do not rely on your own strength. Self-treatment of otodectosis, can lead to serious negative consequences for the animal.

Drugs for the effective treatment of canine otodectosis:

Drops: “Bars”, “Otoferonol Gold”, “Oricin”, “Dekta” and others;

Ointments: sulfur-tar and birch tar;

Injectables: Ivermec 1%, Otodectin.

Before using acaricidal agents, it is necessary to clean the dog’s ears as best as possible, from accumulated scabs. To do this, they are moistened and softened with one of the antiseptic agents (boric acid, hydrogen peroxide, furacilin solution, ear lotions), preventing fluid from flowing into the ear canal.

Having carefully cleaned the skin of the inner surface of the ear and the cavity of the ear canal, from softened scabs, one of the anti-otodectosis drugs is instilled, observing the dosage given in the instructions. Given the development cycle of the parasite, drugs are usually used twice, observing a weekly interval between procedures.

Injectables work most effectively. If the dog has no contraindications, then this is the best treatment option. They ensure the destruction, not only of skin parasites, but also helminths, acts more long-term and reliably than drops, sprays and ointments.

Important: you need to remember that all insecticidal preparations are potent agents and can be dangerous, not only for animals, but also for people. The use of otodectic agents requires strict adherence to the order of application and dosage, according to the instructions and taking into account the weight of the animal.

What is this otodectosis?

Ear mites in dogs are, invisible to the human eye, arthropods, oval in shape, beige in color. Parasitizes the mite on the skin surface of the external ear canal of the dog and the inner surface of the ear.

This, as a rule, causes itching, inflammation, otitis media, often leading to more complex consequences. The parasites damage the top layer of the animal’s skin and feed. blood, lymph, or tissue fluid. Subsequently, these fluids mix with the epidermis and form dark brown crusts.

There are two types of ear mites. Cats, dogs, and many other animal species are parasitized by the scabies mite, Otodectes cynotis. Parasite dimensions, do not exceed 0.5 mm.

  • Egg
  • Larva
  • Nymph, first stage of development (protonymph)
  • Nymph, second stage (telonymph)
  • Adult insect (imago)

The whole cycle (egg. adult tick) takes 18-25 days, the cycle duration depends on the ambient temperature. Outside the shells of the ears, on the body of the animal, that is, without feeding, the parasite can maintain its viability for 22 days. In the environment, at temperatures ranging from 3 to 7 C, and high humidity, it can be vital for about 25 days. At low temperatures, below 3, dies within 5 days.

Home Questions and answers Dogs Diseases and health of dogs

Ear mites, or otodectosis, is a contagious disease in dogs that affects the inner surface of the auricle. Most often, mites can be found in the auricle and external auditory canal. If you do not start treatment, then this can lead to serious complications, such as. otitis media, arachnoiditis (inflammation of the choroid of the brain and spinal cord), perforation of the tympanic membrane, meningitis. There are currently many medicines available to kill ear mites in dogs: injections, ointments, drops and sprays.

Before starting treatment, you need to make sure that the dog really has an ear mite, and for example, does not have otitis media. To do this, the contents of the ears (scraping) are examined under a magnifying glass or microscope.

For the successful treatment of an ear mite (and depending on the type of medication), certain procedures must be carried out:

Before instilling drops in the ears, they must first be cleaned. The hair growing in the ears is cut off, otherwise the medicine will remain on it and not on the skin. If there are crusts, then they must be soaked and then carefully removed. To do this, a solution of cleansing drops (Migstim, Otifri, Klini, Epi-Oti) or lotion (Bars, Otodin, Epi-Otik, Ear Cleaner) is instilled into the dog’s ears. In their absence, you can use 2% hydrogen peroxide, dioxidine, oil (baby, vegetable, vaseline), fish oil, alcohol-containing solutions, glycerin, 0.1% rivanol or furacilin solution, 3% boric acid solution. Then, use a cotton swab (a clean stick is used for each ear) to clean the ear canal. It is better to instill drops warmed up to 30-35’C. After that, you need to massage the ear at the base for a couple of minutes for faster absorption of the medicine.

Drops on the withers are applied only externally. they are applied to the area of ​​the shoulder blades, to the base of the neck or along the dog’s cervical vertebrae. It is easy and simple to use such a remedy, and its effect lasts up to a month. But such drugs are quite expensive and not everyone can afford them.List of drops to the withers: Front Line Spot He, Advocate, Stronghold, Dana Spot He, Phiprist Spot He and others.

The injections are convenient in that there is no need to put drops in (but not clean them) sore ears, which often increase the pain, which makes the dog fearful when cleaning the ears. Once in the bloodstream, the drug not only kills ear mites, but also helminths.

But there are also disadvantages:
– These drugs are quite poisonous, so only a veterinarian can prescribe them. By showing independence, you can poison your dog.
– Products based on ivermectin should not be used to treat collies, shelties and bobtails.
– These drugs can only be injected into adult dogs.
– Do not use injections on weakened animals, as well as for diseases of the liver, kidneys, pregnancy and lactation.

List of injectable drugs: Aversect KS, Otodectin, Ivermek 1% and others.

Ear treatment with acaricidal foams should be carried out at a distance of 10-15 cm for 1-2 seconds.

List of acaricidal foams, sprays and gels: Acrosol, Ivermec, Anti-Flea spray, Amidel-gel, Acaromectin.

Ointments are used to treat damaged areas of the skin of the auricle. When placing the ointment in the ear canal, the auricle is folded in half lengthwise and massaged at the base. For external use, the ointment is applied to the surface of the skin or to the ear at the rate of 0.2. 0.3 g per 1 cm².

List of ointments: aversectin, sulfur-tar, Oridermil, birch tar.

Remember that ear mites can move to other parts of the body, therefore, during treatment, the dog must be treated with insecticidal acaricidal shampoo (Flea Tick Shampoo, Zoolekar, Demos, Bars, DIP-II, Dana, Hartz, Husse Citronella, Bolfo, Phytoelita, etc. ).

Attention! The parasites are quite tenacious and can live in the environment for up to a month. To avoid re-infection, at the same time as treating the dog, it is necessary to process its things (bedding and objects with which the sick animal had contact) and the floor from ticks with any acaricidal agent (Butoks 50, Tsipam, Amit, Allergoff spray, Quick Bayt WG 10, Diazinon S, Suminak).

Risk group: which dogs are most susceptible to otodectosis

Quite frankly, dogs become infected with ear mites much less often than cats. But there is a certain risk group in the case of these pets:

  • Longhaired breeds.
  • Dogs with long ears are very susceptible to tick infestation.
  • In addition, animals with soft and wrinkled skin (Shar Pei, for example) are in a similar situation.

But far from always and not in all cases the breed belonging plays a noticeable role. The combination of the following factors is much more important:

treat, mite
  • Fatness and general health of the pet (however, this is true for thousands of other diseases). The closer the dog is to its normal physiological form, the less likely it is to develop tick-borne infestation. Accordingly, obese and weakened, emaciated animals are equally convenient targets for parasitic ticks.
  • The younger or older the animal, the higher the likelihood of the disease. Age factors have a bad effect on the state of immunity of dogs, and therefore the latter get sick much more often and much more heavily (of course, this applies not only to otodectosis, but also to many other pathologies).
  • Of course, initially sick pets are much easier to “catch” parasites.
  • Nutrition plays an important role. The better the pet’s diet is selected and balanced, the less likely it is that it will develop otodectosis.

What does ear mite look like in dogs

Even experienced breeders often have an idea of ​​what an ear mite looks like in dogs. In general, there is nothing strange about this: the pathogen, that is, Otodectes cynotis, does not differ in impressive size. It can generally only be seen through a microscope.

But there is still a way to see this parasite with the naked eye:

  • It is necessary to take a clean cotton swab and scrape the inner surface of the pet’s auricle thoroughly.
  • Then you need to carefully peel off the cotton wool from it and put it in a small glass vial (a container for antibiotics or eye drops is ideal).
  • After 60 minutes, the container is placed against a black background (for example, against a sheet of colored paper) and, using a good light source, carefully examine the insides of the test tube. If you look closely, you will notice tiny, whitish and “self-propelled” dots. These are ear mites. If you take a more powerful magnifying glass, you can see more details of the structure of the parasite’s body.

One of the interesting features of this tick species is the almost complete absence of sexual dimorphism: the body length of both females and males is approximately 0.45-0.5 mm. This makes them very different from other types of ticks, in which the female is usually much larger than the males (especially after abundant nutrition).

Signs of ear mites in dogs

In general, everything is simple here. All signs of an ear mite in dogs are similar to those for any other hearing diseases:

  • The dog starts scratching his ears. At first, it is mild, but over time, the itching becomes more and more severe. After a couple of weeks (depending on immunity and other factors), he “gets” the animal so much that the dog starts to literally tear his ears. It is not surprising that in sick pets, the auricles quickly become covered with numerous scratches, tears and abrasions.
  • Development of the inflammatory process, in many cases quickly turning into a purulent form.
  • Abundant accumulations of brownish-red deposits. These are the waste products of ticks. Accordingly, the more this “sedimentary rock” is, the more intense the infection.
  • In severe, advanced cases, an ideal environment is created in the ear for the development of pathogenic and, including pyogenic, microflora. In addition, in some situations, putrefactive microflora joins the inflammatory process. In these cases, the dog starts to smell extremely unpleasant. In addition, with advanced otodectosis, the dog constantly shakes its head and ears, which is why droplets of a foul-smelling exudate fly in all directions.

How to treat EAR Mite for your cats and dogs – VET TIPS for Pet Feeders

How to treat an ear mite in a dog at home

Some parasitic diseases in pets have become so boring to breeders that they practically do not pay attention to them. A good example of this is otodectosis in dogs. But the disease is actually very dangerous! Therefore, today we will tell you how you can (and should) treat an ear mite in a dog at home.

Drug treatment

As a rule, drug treatment for ear mites does not cause any particular difficulties. Provided, of course, that the case is not yet too neglected.

There are a lot of preparations for this:

  • The most common drops “Bars”, which are in every veterinary pharmacy.
  • Otovedin.
  • Tsipam.
  • Aurican and other drip preparations designed to be applied directly into the ear canals.

How to properly clean your dog’s ears before using medication

And now we need to talk about how to properly clean the dog’s ears before using basic products. There is nothing difficult in this, but you should always be careful and careful:

  • Use only sterile cotton swabs to clean your ears.
  • When cleaning the ears from crusts and “debris” of waste products of ticks, force cannot be used. Simply put, all the crusts and other pieces must be separated very carefully and gradually. We strongly do not recommend peeling off the scabs, as this will certainly lead to the development of an inflammatory process. To prevent this from happening, you must first soften them with sterile vegetable oil or hydrogen peroxide.

Why is the parasite dangerous?

As we wrote above, many breeders do not worry at all that their pets have ear mites. This is a fundamentally wrong and extremely dangerous delusion. At first glance, “harmless” otodectosis is a rather unpleasant disease. But what is the danger of the parasite?

A number of unpleasant complications:

  • The most common problem is otitis media. over, in many cases, it has a dangerous habit of rapidly deteriorating, turning, for example, into a purulent form. With a particularly “successful” combination of circumstances, the dog may well die from perforation (more precisely, melting) of the eardrum and the ingress of pus directly into the brain. In addition, in recovered dogs, coordination disorders are often observed. This is due to the possible damage to the cochlea and other organs responsible for maintaining a normal body position in space.
  • Complete or partial deafness of the animal. Considering that the ear mite in most cases affects both ears, deafness may well be not only complete, but also bilateral.
  • Inflammation of the external and all other parts of the hearing organs.

Important! Any tick-borne (and generally parasitic) invasions strongly “plant” the immunity of the animal, which is fraught with the development of fungal infections. An ideal environment (warm, damp, lots of fertilizers) is created in the ear for the growth of fungi.

Likewise, the risk of developing tumor pathologies (both benign and malignant) increases significantly.
