Best Dog Foods for Adult Dogs


Save on pet insurance for your pet

You don't have to choose between your pet and your wallet when it comes to expensive vet visits. Prepare ahead of time for unexpected vet bills by finding the pawfect pet insurance.

Dog food manufacturers tailor adult formulas to the specific needs of adult dogs, which are very different from those of puppies, seniors, and pregnant or lactating dogs. That's not to say that any adult dog food will do for your pet, though.

When searching for the right food for your fur-baby, you need to consider your dog's individual nutritional needs and health factors. We'll walk you through the do's and don'ts when shopping for dog food and give you our recommendations for the top 5 adult dog foods on the market.

What to look for in dog food for adults

Low-calorie dog food 

Many dog food formulas have more calories than a typical companion dog needs. Unless your dog is a canine athlete or working animal, experts advise you to steer clear of these calorie-dense diets. Consistently exceeding your pet's daily caloric requirements can lead to obesity and put them at risk of diabetes over time.

For this reason, it's a good idea to start your dog on a low-calorie diet in early adulthood. Restricting calories is difficult when you're feeding high-calorie dog food and can mean your dog gets smaller portions and leaves the dog bowl unsatisfied. To help satisfy your pup’s hunger and caloric needs, experts recommend picking a dog food that contains 350 calories or fewer per cup.

High-quality protein

As you probably know, dogs need protein to maintain muscle mass, but that's just the tip of the iceberg. Protein is fundamental for natural healing processes and regulating hormones and enzymes. Your woofer requires 22 different amino acids for optimal health, and dogs derive 10 of those exclusively from their food (mainly animal protein).

Not all proteins are created equal, though. For instance, chicken meat is easier to digest and has a better nutrient profile than soy protein or bone meal. Moreover, plant-based proteins and bone meals may not provide dogs with enough of the amino acids they need. So how much protein do adult dogs need? According to the Association of American Feed Control Officials (AAFCO) adult dog food should contain no less than 18% crude protein.

Chelated minerals

Vitamins and minerals are key for complete and balanced dog food. However, minerals by themselves aren't super bioavailable. For this reason, many pet food manufacturers add chelated minerals to their recipes.

During chelation, minerals adhere to proteins in order to make them easier for a dog's digestive tract to absorb. Experts are quick to point out that natural sources of vitamins and minerals are preferred, but chelated minerals can ensure your dog is getting what they need from their daily diet.

What to avoid in dog food for adults


Avoid dog food with carrageenan in the ingredients list. This food-thickening agent has FDA approval for use in human and pet food and is especially common in wet dog food. Carrageenan doesn't become dangerous until it mixes with the acids in a dog's digestive tract.

Stomach acid changes the chemical composition of carrageenan and transforms it into poligeenan, a highly inflammatory substance and possible carcinogen in animals. Besides having the potential to cause cancer, studies link this food additive to ulcers and intestinal tumors.

BHA, BHT, and ethoxyquin

Other possible carcinogens commonly found in pet food are the artificial preservatives BHA, BHT, and ethoxyquin. Animal studies have shown a connection between BHT and BHA and tumors of the liver and stomach. Additional studies show that consuming large doses of ethoxyquin affects liver enzymes and can cause kidney damage. 


MSG is a popular flavoring agent that gives food an appealing salty and savory taste. While we know MSG can make dog food more palatable, its use comes with risks.

Numerous studies have linked consumption of MSG to a variety of health conditions in rodents, from liver damage to diabetes. Though the FDA claims MSG "generally recognized as safe," it's best to avoid this unnecessary ingredient altogether.

5 tips for choosing the right food for adult dogs

#1. Buy size-specific formulas.

Dog food brands include size recommendations on the label for a reason. Not only does the nutrient content differ between small and large dog recipes, but the morsels are sized specifically for those dogs as well. To ensure proper nutrition and palatability, choose a dog food that corresponds to your dog's size.

#2. Choose whole grains and veggies over empty-calorie fillers.

Many low-end kibble brands add fillers like corn, soy, and wheat to their recipes to bulk up the product. These ingredients are some of the most common canine food allergens. Avoid recipes with fillers listed in the first 3 ingredients when shopping for pet food, and pick up a wholesome blend of meat, whole grains, and veggies instead.

#3. Consider your dog's oral health.

You must also consider the condition of your dog's teeth when picking an adult dog food. Dogs with fragile teeth may have difficulty eating kibble and may be better suited for a wet food diet.

Most vets recommend dry food for dogs with healthy teeth since wet food can contribute to tartar buildup. On the other hand, the abrasive nature of crunchy kibble can actually combat plaque. Please remember that dry food is no replacement for regular brushing.

#4. Try before you buy.

Instead of buying a big, expensive bag of food that you're unsure if your dog will even like, see if the brand offers trial sizes or free samples — that way, you're not out 50 bucks if your dog turns their nose up at it.

#5. Switch up brands from time to time.

We're sure you'll agree eating the same thing all the time gets stale — and the same goes for your dog. That’s just one reason many vets recommend switching dog food brands every now and then. Some evidence suggests that feeding the same dog food recipes over and over can increase the risk of food allergies.

Finding the right food for your adult dog may take some trial and error, but if you follow these tips, you can rest easy knowing your pet is getting the quality nutrition they deserve. Do you have questions or concerns about your pet's diet?  Click here to chat with a vet today!
