How Long Do Dogs Have Periods?

It is a common misconception that only female humans experience menstruation. However, female dogs also undergo a reproductive cycle, often referred to as their “heat” or “estrus” cycle. Understanding how long dogs have periods is important for dog owners to properly care for their pets and avoid any potential health issues.

The estrus cycle in dogs typically occurs twice a year, although this can vary depending on the breed and individual dog. The cycle involves several stages, including proestrus, estrus, and diestrus. Proestrus is the initial stage, during which a female dog’s vulva will swell and she may exhibit signs of attracting male dogs, such as increased urination and licking of the genital area. This stage can last anywhere from 7 to 10 days.

Following proestrus is the estrus stage, also known as “heat.” This is when a female dog is fertile and can potentially mate. During this stage, the vulva remains swollen, and the dog will often have a bloody discharge. This stage typically lasts around 9 days, but it can range from 3 to 21 days. It is important to note that female dogs should not be bred during their first heat cycle, as their bodies are not fully developed yet.

Diestrus is the final stage of the estrus cycle, during which the female dog is no longer receptive to mating. The vulva will gradually return to its normal size, and any discharge will stop. Diestrus lasts approximately 60 to 90 days, regardless of whether the dog was impregnated or not.
