When Can a Female Dog Get Pregnant During Heat: Managing the Female Dog Heat Cycle

The heat cycle, also known as estrus, can last anywhere from 2 to 21 days, with an average duration of 3 weeks.

During this time, a female dog can become pregnant, as sperm can remain viable inside the reproductive tract for up to 5 days after mating.

It's worth noting that the heat cycle can vary significantly between breeds and individual dogs.

During the fertile window, a female dog will try to spend more time with male dogs, maybe approaching them at the park or on walks, and will also move her tail from a tucked position off to the side to show off her fertility.

The heat cycle has four stages: Proestrus, Estrus, Diestrus, and Anestrus, with Proestrus lasting around 7-10 days, Estrus lasting 5-10 days, Diestrus lasting 60-90 days, and Anestrus lasting 90-150 days.

It's crucial to keep a female dog close during the fertile window to avoid surprise litters, and be extra attentive to her emotional needs during this time.

The vulva swells during Proestrus, but returns to its usual size during Diestrus, and discharge changes from reddish-brown spots to a clear, glistening flow during Estrus.

Female dogs can breed anytime during heat, and the heat cycle occurs about every six months, although the frequency may differ by breed.
