Puppies grow quickly and have special nutritional needs to keep their bodies strong. The most noticeable time is known as the rapid growth stage, which occurs between 2 and 6 months of age. From about 3 to 6 months, most pups will lose their puppy teeth (you might find a tooth near his dish or on the floor; this is normal).

Spaying (for females) consists of an ovario-hysterectomy.
Neutering involves the removal of the testicles. When you bring your puppy to the veterinarian's office for his first thorough examination, have the doctor explain the operation in detail and set up a time to have the procedure done.
