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 may have the surgery as young as 8 weeks of age. Ideally, they will have the surgery before they reach 6 months old. This is the age when females are able to reproduce, so spaying before their first heat (menstrual cycle) prevents any chance of pregnancy.
