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.
Generally dogs will come into heat twice a year (approximately every 6 months). There are, however some that come in once a year, and some three times. We will also commonly see that the first heat is an incomplete one and the dog returns to a full heat about 1 month later.
