You wouldn’t choose a collar, bed or squeak toys for your puppy that are meant for a much larger adult dog, right? Your dog food shouldn’t be formulated for adult dogs either. 

Puppy foods were formulated to ensure that puppies ranging from diminutive Dachshunds to giant Great Danes receive the essential vitamins, minerals and nutrients to grow from small, wriggling puppies into healthy adults.

Puppy vs Adult Dog Food: What’s the Difference?

It might be impossible to tell the difference between a bowl of puppy food and a bowl of adult food, but that doesn’t mean both formulas are the same. 

“Puppies have different nutrient needs than adult dogs,” says Dr. Angela Rollins, clinical associate professor of nutrition at the University of Tennessee Veterinary Medical Center and diplomate of the American College of Veterinary Internal Medicine.

Specifically, puppies need different amounts of calcium and phosphorus; adult foods don’t contain enough of these essential nutrients for healthy bone development in younger dogs, Rollins says. 

Puppy foods also contain higher amounts of docosahexaenoic acid (DHA), an omega-3 fatty acid that puppies need for healthy brain development.

Puppy Food: What to Look For

When it comes to choosing the best foods for your growing (and adorable) puppy, obsessing over individual ingredients isn’t important, according to Rollins.

Instead of reading endless ingredient labels, Rollins suggests looking for two things: the “life stage” listed on the bag and the Association of American Feed Control Officials (AAFCO) seal. Puppies need puppy food, not adult food, to ensure that they receive all of the essential ingredients for optimal growth and development. The AAFCO seal is another indication that a dog food is complete and balanced. In other words, it contains all of the nutrients that dogs require at each life stage and the nutrients are in the correct proportions. Any puppy food with the AAFCO seal is a good choice for a healthy diet, Rollins says.

If you have a large breed puppy—we’re talking about you, German Shepherds, Mastiffs and Rottweilers—look for foods designed with their size in mind. 

Rollins notes that large breed puppies have specific nutritional needs and require foods with the right balance of nutrients. These formulations have higher protein levels and essential fatty acids like DHA that were designed to promote slower, steadier growth; large breed puppy foods are also less calorie dense, allowing growing puppies to eat enough to feel full without overeating.

Puppy Food: Tips and Advice

Puppy eating from bowl

Your puppy needs optimal nutrition for proper growth and development. Follow these feeding tips to keep them healthy.

Use a measuring cup: More than half of dogs are overweight or obese. Measuring out your puppy’s food (instead of filling the bowl and allowing her to graze) can help prevent her from overeating.

Limit treats: Treats are great training tools but avoid offering too many. “Treats shouldn’t make up more than 10 percent of your dog’s daily calories,” Rollins says. Too many treats could also spoil your dog’s appetite, making it harder to get the right balance of nutrients from her puppy food.

Store food safely: Wet food should be kept refrigerated after it’s opened and kibble should remain in its original bag (which lists the expiration date) and stored in a cool, dry place.
