A dog owner should have an idea when the pet will go into heat. The reproductive cycle varies from breed to breed. Generally puberty will occur as early as 6 to 12 months in small breeds and as late as 2 years in large breeds.
Dogs do not experience menopause, either. Because the estrous cycle is so drawn out, female dogs tend to go into heat an average of two times per year. Depending on the size and breed of the dog, the capacity to breed can begin as early as six months of age, or as late as 24 months of age.
