Today some vets will spay/neuter at eight weeks of age, while other adhere to the old practice of six months of age. The average age at which pets are spayed or neutered is four months. Adolescent cats and dogs as young as five months can get pregnant.
Some dogs would come into heat earlier than six months and can get pregnant in the first heat although it is advisable to breed the dog when it is about 2 years old or after the dog has gone into the 2nd or 3rd heat. Small breeds mature faster than large breeds. This means that a Great Dane female can come to its first heat from one to two years of age while an Affenpinscher or a Shih Tzu would go into heat for the first time from 6 to 12 months of age. Breeding the pet to produce a litter of healthy and adorable puppies will be very rewarding.
