Well, you may be surprised to find that there is no simple answer. There are many factors that affect the canine estrous cycle such as breed, age, health and size of the dog. On average, a female dog is in heat for about 18 to 21 days twice a year. Typically, small breeds mature and experience earlier estrous cycles, while larger breeds, which mature more slowly, experience later cycles. Because of this slower maturity, large breeds may only have one estrus cycle (heat) per year.
