📅 What Is a Dog Heat Cycle?
4
A dog heat cycle (also called the estrus cycle) is a natural part of a female dog’s reproductive health. Most dogs go into heat twice a year, but this can vary by breed and age.
There are four dog heat cycle stages:
- Proestrus – swelling, spotting, and hormonal changes begin.
- Estrus – ovulation and mating period; best time to breed a dog.
- Diestrus – end of the fertile window for dogs.
- Anestrus – resting phase before the next heat cycle starts.
LSI Keywords used: dog heat cycle stages, dog in heat symptoms, estrus and proestrus in dogs.
