Different breeds, different needs

If you have a dog, you know that choosing the right food for them is essential. That’s why you might be looking for the best natural dog food or the best grain-free food for your pet’s specific needs. But did you know that size also plays a big role when it comes to the best diet for your dog? Well, it does, which is why you want to be smart about choosing the best large breed dog food if you have an oversized fur baby at home. Before we get into the specific vet-approved recommendations, there are a few things you need to know.

What’s different about large breed dog food?

It really boils down to calories in relation to your dog’s metabolism. “Smaller breed dogs typically have a higher metabolic rate and actually burn more calories per pound,” explains veterinarian Joel Beth Navratik, DVM, former CEO of MRVL Pet Pharmaceuticals. “Large breed puppies need to be calorie-restricted to prevent rapid weight gain.” This is especially important because studies show that if a large breed puppy gains too much weight in his first year of life, he will be much more prone to arthritis in his later years. For that reason, large breed dog food is usually crafted with fewer calories. It also tends to boast bigger pieces of kibble that help slow down a dog’s eating speed.

Should large dog breeds eat a grain-free or a BEG diet?

In case you aren’t familiar with the term, a BEG diet is one that consists of boutique, exotic, and grain-free foods. While the FDA hasn’t released an official statement about the safety of grain-free diets for dogs, they have released statements over the years in response to reports that link pet foods containing lentils, peas, legumes, and potatoes as main ingredients with canine dilated cardiomyopathy (DCM), a serious heart condition; those ingredients are usually what takes place of the grains in certain foods. Because of this, most pet experts are against grain-free diets. “Large breed dogs typically should not be fed a grain-free diet unless prescribed by their veterinarian,” Dr. Navratik explains. Other veterinarians note that many BEG diets aren’t formulated to meet the specific nutrient needs of large breed dogs.

What should you look for in large breed dog food?

You should take several factors into consideration, including your dog’s age, breed, size, and activity level. For instance, large breed puppy foods should have a good amount of protein. “They should have 30 percent protein and 9 percent fat on a dry matter (DM) basis in addition to calcium amounts up to 1.5 percent and phosphorus around 0.8 to 1 percent DM,” explains Michelle Burch, DVM, a veterinarian with Safe Hounds Pet Insurance. “Large breed puppy foods should also not be fed to a dog in all its life stages.”

For adult dogs, you’ll need a diet that provides a balanced ratio of fats, carbohydrates, and proteins. “Pay close attention to the labels on dog food and look for foods labeled ‘complete and balanced,’ which is the best indicator that a food has all the necessary nutrients,” says George Melillo, DVM, Chief Veterinary Officer and cofounder of Heart + Paw. Beyond that, of course, you’ll want to take your dog’s special needs and preferences into consideration, as well as consult your vet. The expert-approved picks on this list will get you off to a good start and help your dog live a long, healthy life.

When it comes to wet food, you should look for one with several sources of lean animal protein and real meat ingredients, such as beef, lamb, and venison, says James Fuller, founder of the pet nutrition site HonestWhiskers.com. The best large breed dog food options, he explains, “have higher protein content to ensure muscle maintenance, as well as development.” That’s why he recommends this American Journey formulation. “It also has whole-food ingredients that provide dense sources of vitamins, minerals, and antioxidants,” he notes. “The organ meat significantly boosts vitamin A content, too.” Combined, these qualities will give your pups tons of energy.

Best for puppies: Royal Canin Giant Puppy Dog Food

“Large breed puppies require dog food that promotes steady growth,” says Fuller, noting that it’s essential for their overall health. “This is the best food for large breed puppies because [it only has] 32 percent protein content, which prevents them from growing too quickly.” He also loves that the food has a healthy balance of fiber sources such as beet pulp, which supports sensitive digestive systems. So, exactly which big puppies is this right for? Those up to eight months old with an expected adult weight of over 100 pounds. Here’s what else you need to buy if you have a puppy.

Royal Canin is a quality brand, so when your large breed puppy reaches adulthood at 15 months, you can graduate to this formulation. “I like it best because it’s formulated to be easily digested while supporting healthy bones and joints,” says Dr. Burch. “It also has added the fatty acids of EPA and DHA, which help promote healthy joints, skin, and coat.” Depending on your dog’s energy level and weight, you can customize the portion size using Royal Canin’s feeding guide, which recommends feeding 75-pound dogs that are moderately active four cups per day.

Best fresh food: BalanceIt.com and PetDiets.com Fresh Food Recipes

Want your dog to get as close to a natural diet as possible? Opt for fresh food. Dr. Burch likes using recipes from websites like BalanceIt.com and PetDiets.com, which, for a small fee per recipe, provide you with customized, vet- and nutritionist-approved recipes specifically formulated for your dog based on his age and breed. “Recipes from these sources will also ensure your pet’s diet meets all the necessary minerals, vitamins, and nutrients needed for a healthy life,” she says, since most dog food recipes you’ll find online are not nutritionally balanced. (In fact, in an independent study of 200 homemade recipes for adult dogs conducted by the School of Veterinary Medicine at University of California in 2013, only 2.5 percent were nutritionally balanced.) On these sites, you can expect tailored recipes for large dog breeds that you can whip up at home, like meals made with beef, brown rice, peas, and carrots.

Best organic: Solid Gold Holistique Blendz Complete Health

As mentioned earlier, large breed dogs typically should not be fed a grain-free diet unless prescribed by their veterinarian, says Dr. Navratik, since many grain-free diets have been linked to cardiomyopathy or heart disease specifically in larger breeds. That’s why she recommends this organic dog food that’s packed with grains and superfoods like oatmeal, pearled barley, and fish, which give your pup lasting fuel, promote gut health, and provide overall immune support. An added bonus that sets this organic dog food apart: It contains 90 million probiotics per pound, which aid with digestion—for more, check out the best probiotic dog foods.

Purina Pro Plan Sensitive Skin And Stomach Via Chewy
via chewy.com

Best for stomach issues: Purina Pro Plan Sensitive Skin and Stomach

If your dog often experiences vomiting, diarrhea, bloating, or constipation, switching to a large breed dog food specifically formulated for sensitive stomachs can help. (Other signs of tummy issues include frequently licking their lips, gulping, or a loss of appetite and energy.) For pets with these sorts of intestinal troubles, Dr. Burch recommends Purina Pro Plan Sensitive Skin and Stomach: “It has produced the best results of any over-the-counter brand I have used.”

It contains easily digestible ingredients—like salmon, rice, and oatmeal—in addition to live probiotics and prebiotic fibers, which make digestion easier. How does it work? The omega-6s from the salmon decrease inflammation and the prebiotics encourage healthy gut flora, Dr. Burch explains. Pro tip: Since dogs with sensitive stomachs often have sensitive skin, too, bathing your pup regularly with the right dog shampoo can make them more comfortable.


  • Easily digestible
  • Natural prebiotic fiber
  • No artificial flavors

Natural Balance Limited Ingredient Large Breed Dog Food Via Petco
via petco.com

Best for allergies: Natural Balance Limited Ingredient Large Breed Dog Food

Common allergy signs in dogs include itchiness, hives, diarrhea or vomiting, sneezing, chronic ear infections, constant licking, and itchy, watery eyes. If your pet has any of these symptoms regularly, your vet may recommend changing his diet. Fuller likes this Natural Balance formulation “because [while] it contains grains, it is gluten-free, helping with larger dogs’ energy and limiting common allergens.” And since it contains only one protein source (lamb) versus multiple protein sources, it limits the risk of new food allergies developing. An added perk: “The kibble is larger than that of other dog foods, [which promotes] proper chewing, while its rough texture assists with cleaning teeth,” Fuller explains.
