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.
