at what age should a dog switch to adult food
Changing from puppy food to adult food depends on the size of your dog as an adult. If he is a small breed and will not exceed 30 pounds, he is mature at 10 to 12 months old. Some small breeds are mature before 10 months of age. Medium breeds are dogs that do not exceed 80 pounds at full growth.
A large breed puppy is expected to weigh more than 50 pounds as an adult, and he may not mature until he is 2 years old. He should continue to be fed puppy food like Purina Puppy Chow for Large Breed Puppies until his second birthday. When switching, to an adult dog food consider the nutritional needs of your dog.
