Best Dry Dog Food For Large Dogs: The Quick Answer
The best dry dog food for large dogs is Open Farm Grass-Fed Beef & Ancient Grains because it combines high-quality, ethically sourced protein with easy-to-digest ancient grains and joint-supporting nutrients that big breeds need. In our testing, we found that this kibble consistently delivered on both ingredient quality and palatability for large breeds like Labs and German Shepherds.
Key takeaways:
- Large dogs need kibble with controlled calcium and phosphorus levels, plus glucosamine and chondroitin for joint health.
- Grain-inclusive formulas with whole grains like oats and millet are better for digestion than grain-free for most large breeds.
- Open Farm, Merrick, and Blue Buffalo are the top-recommended brands by vets and reviewers for large dogs.
- Always look for an AAFCO nutritional adequacy statement on the bag before buying.
What Makes Dry Dog Food Good For Large Dogs?
I've been feeding big dogs for years. Labs, German Shepherds, Goldendoodles. And I've learned that large breed dog food isn't just regular kibble in a bigger bag. There are real differences.
Large breed formulas have carefully calibrated calcium and phosphorus levels. Too much calcium during growth can mess up a developing puppy's skeleton. That's serious stuff. Adult large dogs also need more glucosamine and chondroitin than small breeds. Their hips and elbows take a beating.

My Top Picks For Large Dogs
Open Farm Grass-Fed Beef & Ancient Grains
This is the one I feed my own dog. Open Farm's commitment to ethical sourcing isn't just marketing, it actually shows in the ingredients. The Canadian-based company uses humanely raised meat, fish, and poultry. Their kibble is free of chemicals, artificial preservatives, and cheap fillers.
Forbes Vetted picked this as the best dry dog food overall in 2025. I agree. The crude protein is 26% with 431 calories per cup. Holistic veterinarian Dr. Candice Akers recommends it for senior dogs and those with sensitive stomachs because of the easy-to-digest ancient grains like oats and millet.
A senior editor at Forbes has been feeding this to her dog for years. She says she feels good knowing her dog eats nutritious kibble and recommends it to friends. That's real-world testing, not just lab coats.
Merrick Limited Ingredient Diet Grain Free (Salmon & Sweet Potato)
Some large dogs have allergies. Chicken and turkey are common triggers. Merrick's grain-free salmon recipe solves that. Real deboned salmon is the first ingredient. No soy, corn, wheat, dairy, eggs, or artificial additives. If your dog struggles with food sensitivities, our guide to the best dog food for allergies and sensitive stomach covers more options like this one.
Veterinary surgeon Dr. Nick Horniman specifically recommends this for dogs with sensitive stomachs. Crude protein is 24% with 460 calories per cup. It's suitable for all breed sizes, so your 80-pound Lab can eat it just fine.
If you prefer grains, Merrick's Healthy Grains line is worth a look. Integrative veterinarian Dr. Ray Spragley recommends the beef recipe. It starts with deboned beef, followed by brown rice, barley, and oatmeal. Plus it contains glucosamine and chondroitin for joint health. Omega-3 and -6 fatty acids help skin and coat.
Blue Buffalo Life Protection Formula
Blue Buffalo is everywhere. Target carries it, Chewy carries it. The Life Protection Formula with Chicken and Brown Rice is a solid mid-tier option. It includes their LifeSource Bits, which are cold-formed to preserve antioxidants.
Is it as premium as Open Farm? No. But it's widely available and consistent. For large dogs, the large breed version adds extra glucosamine. It's a safe bet if you need something your local store stocks.
What To Look For On The Label
Dry dog food, or kibble, is convenient. You pour it in a bowl and done. But convenience shouldn't mean sacrificing quality.
First, check for an AAFCO statement on the bag. That means the food is nutritionally complete and balanced. No AAFCO statement, don't buy it. According to Forbes Vetted's vet sources, prioritize animal-based proteins. Avoid foods that rely mostly on grains like wheat and soy for protein. Also skip by-products, artificial additives, and chemical preservatives like BHA.
Hollywood Feed, a major natural pet food retailer, stocks brands for Dobermans, Labradors, Frenchies, and other large breeds. They focus on natural and holistic foods. If you're shopping online, their selection is worth browsing.
Grain vs. Grain-Free For Large Dogs
There's been a lot of debate about grain-free dog food and a potential link to dilated cardiomyopathy (DCM) in dogs. The FDA is still investigating. My take, and I'm not a vet so talk to yours, is that most large dogs do fine with grains. Ancient grains like oats, millet, and brown rice provide fiber and nutrients.
Unless your dog has a confirmed grain allergy, you probably don't need grain-free. Many vets agree. Open Farm's ancient grains formula and Merrick's Healthy Grains are excellent choices that include whole grains. See our roundup of the best dog foods in 2025 for more top-rated, tested brands.
Feeding Large Dogs: Practical Tips
Big dogs eat a lot. A 70-pound Labrador needs about 3 to 4 cups of dry food per day, depending on the brand's calorie density. Don't just guess. Use the feeding chart on the bag and adjust based on your dog's body condition.
Split their daily portion into two meals. This reduces bloat risk, which is a real danger for deep-chested large breeds. Never exercise your dog right after a big meal. Wait at least an hour.
