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 will go into heat twice a year with the second Estrus cycle coming 5-6 months after the first. One unique difference between dogs and humans is that if left unspayed the female dog will go into heat her entire life as they do not experience any sort of menopause.
