Is my Puppy Still a Puppy?
Life-stage transition for dogs
While they may grow up and begin to look less like a typical Puppy, Puppies continue to need extra nutritional support for quite a lot longer than you may think. Puppies mature into adults at a different time, which means that a large breed will mature into an adult at about 15 months, while smaller breeds will be puppies for only 9 months. So, you’ll need to feed a larger breed specially formulated Puppy food for much longer than you would a smaller breed.
They're not Puppies forever
Puppies experience many physical changes as they develop into adult dogs. Physical size and shape change as the bones lengthen and harden, joints mature and muscles, ligaments and tendons all grow to adult size. The coat changes from a soft, fluffy one to a denser adult coat. Baby teeth fall out and are replaced with permanent adult teeth. And the immune system matures so your dog is ready to handle the big, wide, outside world.
