As a rule, estrus occurs with pauses of 6-8 months. A number of factors. for example, genetic predisposition, current condition. determine when a cycle begins. They also determine the behavior of dogs during their first estrus.

The duration of proestrus, the onset of estrus, is about 9 days. The behavior of the dog during estrus in proestrus is manifested in constant marks. This is done so that males perceive pheromones in the dog’s urine.

The initial period of estrus is manifested in the scaring away of males. She can growl, jump from them.

The second phase is estrus, its duration is 9 days. The behavior of dogs during the estrus of the second period consists in active flirting with males. If it is touched from behind, it immediately removes its tail, bends its front legs.

The third stage of the cycle is called metestrus. The dog begins to restore its normal physiological processes. The stage lasts about 150 days. At this time, she stops allowing males to approach her.

By the way, it is not only the behavior of the dog that changes during estrus. Her appetite practically disappears, she refuses to eat.

At the fourth stage, anestrus, complete sexual rest begins. The duration of this period is also about 150 days.

Avoid complexity

But for a dog to be able to bear offspring, it must be mature both sexually and physiologically. And this happens around the second year of life.

Aggression manifests itself in the behavior of the dog during estrus. It is aimed at both people and other animals. Some pets have a discharge of pale flowers from the loop. They often begin to mark in the home and on the street.


It is important to bear in mind that if the bitch has not passed her first estrus by the age of 2 years, you should contact your veterinarian. It is considered normal if your pet is in heat once or twice a year. When this happens more often, this is probably evidence that a hormonal imbalance has occurred, which must be treated in order to avoid negative phenomena in the dog’s health.

Difficulties of the first heat

It should be borne in mind that the most important stage in the life of bitches is the first heat. It usually begins after the change of teeth. Bloody discharge appears, the pet is unlikely to communicate with males, but this does not mean that you should not worry.

If the owners want to subsequently breed puppies, you need to track the moment when the first estrus begins. After all, they begin to knit pets in the third cycle. As a rule, hosts mark the dates of empty events on the calendar.

Compliance with frequency

Care must be taken to keep the pet clean at this time. Usually they are clean, but bitches who live at home will need extra care. Most likely they will stay in their sleeping place. But you will need to constantly change its litter or clean it. Even the behavior of a Spitz dog during estrus is of such a nature that many traces will remain throughout the apartment.

There is no need to punish her for this. In such cases, some of the owners put on special panties on the pet. With such clothes, there will be no traces in the apartment and carpets, furniture, floor will remain clean.

Why does the licking mechanism arise and what does it serve

We all come from childhood. And dogs too. If you have ever had puppies with you, then you probably noticed that the first thing a mother does is lick them, helping to get rid of the remnants of the membranes and stimulating the development of respiratory function in babies. In the future, maternal licking is designed to improve the functioning of the puppy’s gastrointestinal tract and keep his fur clean until the dog’s child matures and is strong enough to do it on its own. And also licking, like motion sickness in humans, has a calming effect.

Thus, licking is the first way a puppy will recognize a contact with another creature. Later, he begins to use it to signal that he is hungry or needs care.

Now let’s see what this behavior can mean when a dog licks a person.

The dog wants to help

Dogs are gregarious animals, and therefore mutual assistance is not alien to them. That is why a pet may try to lick wounds (this is how dogs heal themselves) or lick naked areas of human skin, trying to understand whether he is alive, make him breathe or not sleep, which in critical situations can really be justified.

Your pet is afraid

Some dogs, frightened by loud noises, naturally seek protection from their leader-owner. Licking, accompanied by whining and the desire to climb into your arms or into bed, it is likely that the pet is scared and asks to calm him down.

The dog shows his love

Licking can indeed signal a special relationship between a dog and its owner or family member (from a dog’s point of view, consider a pack). In the event that the licking is accompanied by joyful cries of the pet, active wagging of the tail, the desire to jump into your arms, this is an expression of love.

Why do dogs lick their owners

Dog kisses evoke affection in us, owners of four-legged pets. After all, we ourselves are inclined to express with the help of kisses a special attitude towards those who are dear to us. However, at the same time, it is not worth overhumanizing the dog. This is a completely different being, which perceives both the world and us in it in a completely different way. Therefore, it will be useful for the owners of furry friends to learn about other reasons why a dog licks a person. And also what signals this pleasant gesture can send him.

The dog reacts to smell

Unlike humans, who perceive most of the information through the visual channel, in a dog, the most important of the senses is the sense of smell. Its capabilities for our four-legged brothers are many times greater than that of humans. Therefore, we may not even feel that we smell particularly pleasant or unpleasant for the dog. In this case, with a lick, she tries to wash us or understand where the person was.

The dog is lonely

If you just sit quietly or are doing something, not paying attention to the pet, and he suddenly comes up and starts licking you, this may indicate that in this way the dog wants to draw attention to himself. Indeed, the wet tongue of the pet on the skin is really hard to ignore!

If you live in a house with wood or marble floors, then removing stains with a regular mop shouldn’t be too difficult. You should also provide the dog with a suitable bedding or towels, especially if he can sit on furniture. Or you can also purchase dog diapers (pictured).
