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.
