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.
Typical Duration of Heat Cycles. Canine heat cycles generally last two to three weeks, indicates Vetwest Animal Hospitals. The exact lengths of heat cycles differ with every dog. While male dogs are drawn to females from the first days of their heat cycles, the females don't accept mating advances until a little time has passed. Female dogs are generally only open to mating with males for roughly half the time of the heat cycle, according to the ASPCA. They typically become fertile between nine and 16 days after the start of heat, when they begin to ovulate.
