When Do Female Dogs Get Their Period: Understanding the Estrus Cycle

Female dogs, like their human counterparts, go through a reproductive cycle known as the estrus cycle. This cycle, commonly referred to as a dog’s “period,” involves several stages and hormonal changes. Understanding when female dogs get their period is crucial for dog owners to ensure proper care during this time. Let’s delve into the details of the estrus cycle and answer some frequently asked questions.

The Estrus Cycle:
The estrus cycle consists of four stages: proestrus, estrus, diestrus, and anestrus. The entire cycle lasts approximately 21 days, but the bleeding or discharge, commonly known as a dog’s “period,” occurs during the proestrus and estrus stages.

When Does It Start?
The onset of the first estrus cycle, or “heat,” in female dogs varies depending on breed and size. Generally, it starts between six to twelve months of age, although small breeds may experience it as early as six months, while larger breeds may begin around twelve to eighteen months.


1. How long does a dog’s period last?
The bleeding phase of a dog’s period typically lasts around 7-10 days. However, this duration may vary from dog to dog.

2. How often do female dogs get their period?
Female dogs usually experience their period twice a year, although this can also vary. Smaller breeds may have more frequent cycles than larger breeds.

3. Can I prevent my dog from getting her period?
While it is possible to prevent a dog from getting her period through spaying, it is recommended to consult with a veterinarian to discuss the potential health benefits and risks associated with this procedure.

4. How can I tell if my dog is on her period?
During the proestrus stage, you may notice a swollen vulva and a bloody discharge. When in full estrus, female dogs may exhibit behavioral changes, such as increased restlessness or attraction to male dogs.

5. Should I restrict my dog’s physical activities during her period?
While it is not necessary to restrict your dog’s activities, it is advised to keep her on a leash during walks to prevent unwanted mating. Additionally, avoid taking her to dog parks or places where male dogs are present.

6. Can I use menstrual products for my dog?
Using human menstrual products is not recommended for dogs. Instead, consider using specially designed doggie diapers or disposable pads made specifically for dogs in heat.

7. Is there anything I should do to help my dog during her period?
Ensure your dog has a comfortable and clean area to rest. Regularly clean her genital area to prevent infections, and consult with a veterinarian if you notice any unusual symptoms or behavior.

Understanding when female dogs get their period and being prepared for their reproductive cycle is essential for responsible dog ownership. By providing the necessary care and attention, you can ensure your dog’s well-being during this natural process. Remember to consult with a veterinarian for any specific concerns or questions related to your dog’s individual needs.
