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 indeed can mature at both earlier and later points than 5 months, but the majority of them go into their initial heat cycles -- and therefore gain the ability to get pregnant and bear young -- when they're in the range of 6 months and 1 year old.
