A female dog is called a bitch and a female used for breeding is called a brood bitch. Generally, a male dog is simply referred to as a dog until he is able to sire puppies, at which time he is called a stud dog.
After birth, dogs are considered puppies until they reach 12 months of age at which time they become adult dogs.
