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.
Dogs can get pregnant during their first heat cycle, but this is not advisable as a 6-month old dog is not yet fully grown/mature, and complications for the mother and the puppies are more likely.
