How Long Does a Dog Bleed When in Heat?

A dog in heat can bleed for around 7 to 10 days. During this first stage of the reproductive cycle, the female will not accept a male.

Does a dog bleed the whole time in Heat?

Keep a leash handy, because your dog may have to urinate more when she's in heat. You may also observe that her vulva is large, red, or swollen with some bleeding or blood-tinted discharge. Your dog will only bleed for around half of the total cycle, usually 7 to 10 days.

How long after my female dog stops bleeding is she in heat?

After about 9-10 days, the bleeding will become more watery, or stop. It is at this time your female will, most likely, be at her most fertile. This proestrus stage can last as long as 20 days in some dogs. So the end of bleeding can be a more useful indicator of peak fertility.
