How Often Are Dogs In Heat

Understanding Your Dog’s Heat Cycle

As a caregiver, you’re entrusted with the responsibility of understanding your dog’s health. As such, it’s essential to grasp the intricacies of your dog’s heat cycle, also known as the estrous cycle. Dogs usually go into heat twice a year, but this can vary based on breed and individual dog. The heat cycle lasts about three weeks, but again, this can differ from dog to dog.

  1. Proestrus: The first stage, lasting 7-10 days. You’ll notice swelling of the vulva, and possibly a bloody discharge.
  2. Estrus: The second stage, lasting 5-9 days. This is when your dog is receptive to mating.
  3. Diestrus: The third stage, lasting 60-90 days. If your dog has mated, this is the pregnancy period. If not, her body will return to normal.
  4. Anestrus: The final stage, lasting 15 weeks. This is the rest period before the cycle starts again.

The Impact of Breed and Size

Understanding the impact of breed and size on the heat cycle is crucial. Smaller breeds may go into heat three times a year, while larger breeds may only go into heat once a year.

Breed Size Heat Frequency
Small 3 times a year
Medium 2 times a year
Large 1 time a year
