How Long is the Heat Cycle? In this phase, the female dog in heat usually rejects any male dog trying to approach her.
STAGE 2: In 5 to 15 days, the female dog lets the male dogs smell their vulva, a gesture that means the ovulation has begun. During this stage, the bloody discharge stops but the vulva will remain inflamed. In case of pregnancy, this will be the longest stage which can last for about to days which is the period of pregnancy and lactation for Shih Tzus.
Common Signs of a Shih Tzu Being in Heat You might be a new owner or have a Shih Tzu rescue that has not been spayed so here are some common signs that might help you out: Her vulva might enlarge 2 or 3 more times its normal size. There will be a discharge that varies from light to moderate. The colour of the discharge can be from whitish-pink to red. Male dogs will be interested in your female Shih Tzu, even stray dogs may hang out around your yard, garden or doors.
Unneutered male dogs will be able to detect female dogs in heat — they can literally smell them up to 3 miles away. With this in mind, we recommend that you keep your female dog in heat inside the house as much as possible. Mild mood changes will be observed. Some female dogs will have nesting tendencies which means that they will be moving objects to their bed or resting spot. Others will be withdrawn or quiet.
Look for unusual behavioural changes. Joey Baggadoughnuts, female. Photo courtesy of David Small. When Does It Begin? Small toy sized dogs like the Shih Tzu typically have their first heat relatively early. It generally happens between the young ages of 4 and 7 months old.
It does surprise many owners to know that their female will still be a puppy when she first enters a cycle. If you have an un-sprayed female Shih Tzu and she has not entered her first heat by the one year mark, you will want to alert the veterinarian. With the Shih Tzu, it will be normal to have a heat cycle every 4 to 8 months.
This averages out to two or sometimes 3 times per year. It is important to note that even senior dogs still enter heat; the canine equivalent of menopause typically does not occur.
This said, discharge for a senior may be lighter than when she was younger and the cycles may be spaced more apart. Nevertheless, this is one reason why spaying is recommended, since even older dogs can become pregnant.
The average heat cycle lasts from 2 to 4 weeks. You may not notice all of the signs for this entire period; however, even if there are no obvious signs near the beginning or end of the cycle, a female can still become impregnated.
Until you are used to knowing when your female Shih Tzu is entering her heat cycle, signs may be hard to spot at first, particularly if discharge is light. Her vulva will become swollen. It may enlarge 2 or even 3 times its normal size. Owners are encouraged to take note of what the vulva looks like when a dog is not in heat, so that they will be able to ascertain the difference.
This will vary from light to moderate. In many cases, this will not be visibly noticed by looking at a dog; however, over the course of a few hours discharge will be accumulating on bedding and other areas where the dog is resting. The color of the discharge can range from whitish-pink to red. So a Shih Tzu might have her very first heat cycle as early as six months old, which is well in advance of the time she would be considered an adult dog by all other measures.
As Banfield Pet Hospital explains, there are four distinct phases or stages to the typical Shih Tzu heat cycle. Proestrus can last anywhere from seven to 21 days. The estrus period typically lasts from five days to two weeks. Once again, when your Shih Tzu enters the actual estrus phase and becomes fertile, you will see some or all of the following changes in her body and behavior:. At this time, even if she mates she is no longer fertile and cannot conceive.
This cycle can last anywhere from 60 to 90 days. However, she will likely still be producing pheromones at some level, which will still be able to attract male dogs to your yard. The final stage of the heat cycle is anestrus.
Many people who choose the Shih Tzu breed do so just to enjoy the wonderful qualities of these companion canines. They have no intention or desire to breed Shih Tzus. This is the hands-down best reason to have your Shih Tzu female spayed.
