Dry Dog Food
Some dry dog foods for small dogs have compositions that are identical to those for larger dogs, but the dog food size is smaller which makes it easier for smaller dogs to chew.
Read the label to determine what ingredients are in the dog food. They are generally listed in order of quantity.
Choose a dog food with high quality ingredients. Watch out for by-products (useless and hard to digest) which only are added to maximize the amount of protein.
