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.
Most dogs are pregnant for between 58 days and 64 days. The due date varies slightly depending on the breed and size of dog as well as the size of the litter she is carrying, but vast majority of dogs will give birth on the 63rd day.
