When will a dog's period end? - in detail
The duration of a female dog's heat cycle, also known as estrus, can vary depending on several factors including age, breed, and overall health. On average, a dog's heat cycle lasts between 18 to 21 days, though this can be shorter or longer in some cases.
During the heat cycle, there are four distinct phases: proestrus, estrus, diestrus, and anestrus. The first phase, proestrus, typically lasts about 9 days and is characterized by a swelling of the vulva and a bloody discharge. This is usually when male dogs become very interested in the female.
The second phase, estrus, is the period during which the female dog is most receptive to mating. This phase generally lasts between 9 to 15 days. During this time, the vulva becomes less swollen and the discharge may decrease or change color. It's crucial to note that a female dog can become pregnant even if she doesn’t display outward signs of being in heat.
Following estrus is the diestrus phase, which typically lasts about 60 to 90 days. During this period, the discharge disappears and the vulva returns to its normal size. If the female dog has mated successfully during estrus, she will enter pregnancy. If not, her body will prepare for a new heat cycle.
The final phase is anestrus, which is a time of sexual inactivity that can last between 4 to 5 months. After this period, the cycle begins again with proestrus. It's important to monitor your dog’s heat cycles, especially if you are considering breeding her or want to prevent unwanted pregnancies. Regular veterinary check-ups can also help ensure your dog remains healthy throughout each cycle.
