Is A Dog Still In Heat After Bleeding: Understanding Canine Estrus

Is a dog being in heat the same as a period? When a female dog enters her heat cycle, which is known as estrus, she does indeed have a bloody discharge from her vulva, resembling a human period or menstruation in this regard. However, it’s important to note that the comparison stops there. Unlike humans who typically have a menstrual cycle every 28 days on average, a dog’s estrous cycle is significantly longer, spanning approximately six months or even more. Furthermore, a dog’s heat cycle consists of four distinct stages. This cycle of reproductive readiness and hormonal changes is quite different from the human menstrual cycle and plays a crucial role in canine reproduction and fertility.

How long a dog remains in heat after the cessation of bleeding can vary, typically lasting around 7 days but differing between individual dogs. Following the conclusion of the bleeding phase, the dog transitions into the estrus phase, during which she becomes fertile and receptive to a male partner. On average, this estrus phase lasts about 9 days, but it can vary significantly, spanning anywhere from 5 to 20 days. Consequently, a dog’s total heat cycle, encompassing both the bleeding and estrus phases, typically ranges from 2 to 4 weeks. The specific duration can vary from dog to dog, making it essential for pet owners to monitor their dog’s behavior and signs of fertility carefully.
