Best Answer: Dogs are in heat for 21 days. There are three distinct stages of the heat cycle. The first one is the âProestrusâ and it is during this stage the owner will often notice the bleeding from the vulva. The bleeding itself can be slight or she can leave evidence of her condition everywhere she sits or lays.
Many times the dog's heat cycle, better known as estrous cycle, seems to be quite unpredictable. The first heat generally occurs around six months in small, medium dogs and around 12-18 months in larger breed dogs. However, It is not unheard of some giant dog breeds going into heat at around 30 months of age.
