Understanding the Canine Heat Cycle
You may be surprised to learn that the heat cycle in dogs, also known as the estrous cycle, is quite different from humans. Unlike humans who are sexually receptive throughout their menstrual cycle, dogs only experience this period of fertility for a short time twice a year. This period, referred to as ‘being in heat’ or ‘in season’, is when a female dog is receptive to mating with male dogs.
Timing and Duration of Heat Cycle
The length of the canine heat cycle can vary widely between different dogs. On average, you can expect your dog to be in heat for anywhere from two to four weeks. The heat cycle generally follows this pattern:
- Proestrus: Lasts approximately 9-10 days. Your dog will start to attract males, but is not yet receptive to them.
- Estrus: Lasts 5-9 days. This is the stage when your dog is receptive to males and can become pregnant.
- Diestrus: This stage lasts 6-10 weeks. If your dog has become pregnant, this is the stage where she will carry her puppies. If she has not become pregnant, her body will begin preparing for the next heat cycle.
- Anestrus: This is the resting stage between heat cycles, lasting around 15 weeks.
Signs Your Dog is in Heat
There are several signs you can look out for to tell if your dog is in heat:
- Swelling of the vulva
- Changes in behavior, such as increased affection or aggression
- Frequent urination
- Vaginal discharge
- Bleeding, which is often less heavy than a human period
Managing Your Dog’s Heat Cycle
If you are not planning to breed your dog, it’s important to manage her heat cycle responsibly to avoid unwanted puppies. Here are some tips:
- Keep your dog indoors or on a leash when outside to prevent unwanted attention from male dogs.
- Consider using doggy diapers to manage bleeding.
- Consult with your vet about the possibility of spaying your dog to prevent heat cycles altogether.
