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.
The dog will then continue to go into heat approximately every 6 months or twice per year. Most female dogs are in heat for 18 days, although male dogs are only interested in the female dog for about half of this time. It is recommended that if the owner does not intend to breed the dog, then she should be spayed either before or after her first heat cycle.
