Usually, black lab gets her first heat cycle at the age of 6-8 months like other dogs. This heat cycle can be of 3 weeks and repeated after 6 months. When dogs get their heat cycle, some signs are observed. These can be frequent urination, restlessness, vaginal swelling and vaginal bleeding.

Vaginal bleeding during heat cycle of dogs can stay for 7-10 days. After this bleeding periods, dogs show flagging that is invitation to male dogs for mating. If this mating is successful then she can remains pregnant for 63-66 days, otherwise, she will again come in to heat after 6 months. In case of pregnancy and delivery of puppies, her next heat cycle will be on schedule time.
