How to count a dog's heat cycle? - briefly

To count a dog's heat cycle, observe for signs of estrus, such as vaginal discharge and swelling of the vulva. The entire heat cycle typically lasts around 18-21 days, with ovulation occurring around day 10-14, depending on the breed and individual variation.

How to count a dog's heat cycle? - in detail

Counting a dog's heat cycle, also known as estrus, involves tracking several key stages. This cycle is crucial for understanding your dog's reproductive health and planning breeding or preventing unwanted pregnancies. Here's a step-by-step guide:

  1. Proestrus (Days 1-9): The heat cycle begins with the proestrus phase, where the dog's body prepares for ovulation. During this time, you might notice subtle changes such as swelling of the vulva and a slight bloody discharge. Your dog may also exhibit behavioral changes like increased urination or restlessness.

  2. Estrus (Days 9-12): This is the fertile stage of the heat cycle, where your dog will be receptive to males. The vulva will appear more swollen, and there may be a clear or straw-colored discharge. Your dog might also start to "flag" her tail, which means lifting it and moving it from side to side to signal her readiness to mate.

  3. Diestrus (Days 12-70): After the estrus phase, your dog enters diestrus. During this period, the vulva returns to its normal size, and any discharge should stop. If your dog is not pregnant, her hormone levels will drop, and she may experience a false pregnancy, exhibiting symptoms like nesting behavior or even producing milk.

  4. Anestrus (Days 70-90): The final stage of the heat cycle is anestrus, where your dog's reproductive system is at rest. No signs of heat are present during this phase, and your dog will not be receptive to males.

To accurately count your dog's heat cycle, monitor her behavior and physical changes closely. Keeping a log or using a tracking app can help you record observations and predict when the next cycle will begin. If you plan to breed your dog or want to prevent unwanted litters, understanding and counting the heat cycle is essential.
