How long do puppies bleed after their first heat?

Puppies typically do not experience a heat cycle until they are older, usually around six months of age. When a female dog goes into heat, she may bleed for about 7 to 10 days. The bleeding can vary in intensity and duration depending on the individual dog. After the heat cycle, the bleeding should stop, and she will not bleed again until her next heat cycle, which occurs approximately every six months.
