Can I Feed My Adult Dog Puppy Food?

There are many brands of dog food available. Within each brand, you will find a variety of types, including puppy, adult, weight control and senior. If you are wondering whether you should give your adult dog the puppy food he likes, the American Society for the Prevention of Cruelty to Animals and other experts say "no."

  1. Dietary Requirements

    • According to the University of Missouri College of Veterinary Medicine, a dog's dietary requirements change depending on its stage of life and activity level. A puppy requires high levels of protein and other nutrients to develop its muscles and bones.

    Warning

    • The higher levels of nutrients in puppy food can hurt an older dog. For example, experts say high levels of protein in puppy food can affect organs such as the kidneys and shorten a dog's life. Similarly, adult dog food does not have the proper amounts of nutrients puppies need.

    Effects

    • If you feed your adult dog puppy food, your dog has an increased risk of becoming obese. Just like in humans, obesity can lead to various health problems in dogs. Among other things, obesity stresses your dog's heart, lungs and joints. It also increases the risk of certain types of cancer.

    Time Frame

    • Different size dogs are considered to be ready for adult food at different ages. But some nutritionists worry that giant breed puppies might grow too quickly if they are fed only puppy food. Some recommend mixing adult food with puppy food for large breeds.

    Changing Foods

    • To switch from puppy to adult food, you can mix the types of food over a few days, gradually increasing the proportion of adult food. It is best to consult with your veterinarian before making any changes.
