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.
If your dog is bred during this period there is a high likelyhood that she is pregnant. A dog's gestation period is generally 63 days. However, dogs can deliver their pups between 58-68 days. If you choose to have your pregnant dog spayed it is best to have her spayed early in her pregnancy.
