But we should know how long Shih Tzu is in Heat. You must be wondering what the heat cycle means or heat cycle in dogs. So, the Estrus or heat cycle is the maturation of the reproductive organs of dogs.

Normally, this is the time when a male-female canine becomes young and starts menstruating like humans. In which vaginal bleeding occurs, and during this period, the female dog is quite ready to conceive. In these flat-faced dogs, the heat cycle begins between seven and 12 months, and in some dogs, between four and 12 months, it lasts a full 23 days, including their vaginal discharge. The first heat cycle of Shih Tzu is definitely a bit difficult in dogs because some dogs get creams, and their behavior changes completely.

The pet owner should take special Care of their dog during this period concerning female food and drink and keep them away from the male dog if they have a female spay. Let’s know all the problems a female dog has to face, what phases she goes through, and how long a dog’s heat cycle lasts!

The heat cycle can occur in shih tzu between three months and 12 months in small breed dogs, with vaginal bleeding. The discharge blood color varies from dark red to white discharge, which is normal, with a heat cycle of about three weeks.

As the female dog becomes young, she goes through many behavioral changes as well as physical and hormonal changes that make some dogs lonely. During the heat cycle, they like to rest and Avoid interactions. The SHIH TZU heat cycle is divided into four phases, the duration of which is different, and the hormonal changes in each phase are different.

Proestrus:

This is the first stage in which there is no vaginal bleeding; only the vulva swells and gets ready for the next phase in which there is bleeding. During this phase, this female dog attracts other male dogs towards her, but at this time, the ovaries are not ready for receptive mating. This is the phase in which maximum body changes occur, and the dog’s behavior is completely changed.

This is the second stage, which we also call the heat stage. Our beloved shih tzu are completely ready for receptive mating because their ovaries are completely fertile. Vaginal discharge can be noted between this phase, the hormone level reaches the peak, and ovulation starts from the ovaries. At this time, this phase can be a bit difficult for dogs as they are a bit uncomfortable due to staining and bleeding.

This is the third phase in which the fertility period is over; now, the hormone level starts to decrease slowly, and the body starts to return to its normal state. This phase is also slightly different in dogs because it causes them to cramp, and a sudden change in behavior can be felt.

This is the last stage of the heat cycle in which the sexual behavior and sexually active period end; at the same time, the hormonal activity also ends, and the reproductive organs of dogs return to their original state. This phase lasts until the second heat cycle stage starts.

The menstruation period or sexually active period in dogs is slightly different from in humans. Dogs live in Heat for a long time, which has different phases. First, they prepare themselves, then their ovaries ovulate, causing ovulation, bleeding, and the release of hormones that compel them to mate with the male dog; and if mating fails, the ovaries slowly discharge the ovules in the form of blood. Remember, how often does a Shih Tzu go into Heat? Female dogs go through heat cycles twice a year. The overall length of the heat cycle also depends on many other factors, such as diet, age, and body weight.

  • If your dog is on a very good diet, he may start the heat cycle early, around four to three months, and, surprisingly, these dogs mature so quickly when considered as puppies.
  •  With aging, this female heat cycle intensity decreases and thus is no longer active. If your dog is spayed, they can reproduce till the last age, so we should try to unspayed them by removing the ovaries or by removing the testes through surgery.
  • The dogs whose weight is higher have a little problem in conceiving and mating, and at the same time, there are many heat cycle problems in them, so you should take special Care of the weight of your small breed dogs.
  • The duration of the heat cycle is three weeks, which lasts about 23 days, and after that, after four to five months, these dogs show the heat cycle again, which depends on their internal condition. 

NOTE:

In some dogs, the heat cycle starts even in 12 months, so there is no need to worry about it, and in some dogs, the heat cycle starts even in four months.
