When a female dog is “in heat,” it means she is ovulating and can breed and get pregnant. Dogs can go into heat when they are as young as 6-8 months of age, which means if they go into heat and have sex with a male dog, then they can get pregnant, even if they themselves are growing still. Show The first heat cycle often is missed by pet parents, which is why many veterinarians advocate for spay surgery at 6 months of age to prevent unwanted pregnancies. Heat cycles vary depending on the dog’s age, size and breed. Small dog breeds can cycle every 3-4 months, medium and large breeds typically cycle every 6 months, and giant breeds may only cycle every 6-12 months. Older female dogs may cycle less often than younger dogs. Bleeding during proestrus typically lasts around 7 days.
