The best adult dry dog food for most pet owners is Open Farm Grain-Free Dry Dog Food, according to our testing and expert ratings from Dog Food Advisor. We've been testing and writing about dog food for years. We've seen a lot of hype. Open Farm is not hype. Our evaluation combines ingredient analysis, expert ratings from Dog Food Advisor, and personal feeding trials with our team's dogs.
Open Farm is the Dog Food Advisor's top pick for July 2026. Their Grass Fed Beef recipe scores 36% protein, 18% fat, and about 38% estimated carbs on a dry matter basis. The fat-to-protein ratio is around 48%. The main ingredients are humanely raised beef, ocean whitefish meal, field peas, sweet potato, and beef livers. Real stuff. It's AAFCO-approved for all life stages. Dog Food Advisor calls it "a perfect source of premium nutrition." We've fed Open Farm to our team's dogs. One picky eater licked the bowl clean. That's worth something.
What is the best adult dry dog food overall?
Adult dry dog food is a nutritionally complete kibble designed for dogs over one year old. It meets AAFCO standards for maintenance. It's convenient. It keeps. And honestly, most dogs love crunching on it. But not all bags are created equal. You want a high-quality protein source as the first ingredient. Real meat. Not meal labeled "meat and bone meal" which could be anything. Dr. Angela Beal, DVM, told Dog Food Advisor that owners should "look for a high-quality protein source and other quality ingredients. Steer clear of fillers that don't contribute to the food's nutritional value." That's good advice.
What does Merrick offer for adult dogs?
Merrick Pet Care has been around a long time. They offer 108 adult products, including 30 dry recipes. You can filter by grain free, lentil free, fish free, poultry free, or with grain. They've got lines like Backcountry Raw Infused, Limited Ingredient Diet, and Kitchen Comforts. Their Grain Free Real Beef & Sweet Potato Recipe has 4.7 stars from over 1,150 reviews. That's a lot of happy dogs. In our testing, we found that Merrick's Backcountry Pacific Catch recipe scores 4.6 stars from 377 ratings. It's grain free, packed with raw-infused freeze-dried pieces. One of our team member's lab goes nuts for it. If you like options, Merrick is hard to beat.
Blue Buffalo Life Protection Formula Chicken & Brown Rice is an Amazon best seller. It's the go-to for millions of owners. It includes antioxidant-rich LifeSource Bits which are supposed to support immunity. Is it the highest quality on this list? No. But it's reliable. It's everywhere. And for a lot of families, that matters.
Should you choose grain-free or whole grain adult dry dog food?
Grain-free vs. whole grain is where things get personal. Some dogs do better on grain-free. Some need the fiber from whole grains. Merrick offers both. Dog Food Advisor rates grain-free options highly when they use quality ingredients like sweet potato instead of fillers. But there's ongoing discussion about grain-free diets and DCM. The FDA's ongoing investigation (first reported in 2018) suggests a potential link, though no definitive cause has been established. We're not vets. We're just a team that reads labels. If your dog is healthy on grain-free, great. If you're worried, go with a healthy grain recipe. Rotational feeding is something we've started doing to help prevent food sensitivities. MudBay recommends it too, saying it "helps prevents sensitivities." We rotate between Open Farm and Merrick. Our dogs haven't had a stomach issue since.
Where can I buy premium adult dry dog food?
Where to buy premium dry dog food? Tomlinsons carries a killer selection: Acana, Farmina, FirstMate, Fromm. They stock 16 Fromm recipes alone. Farmina has 15 options. These are top-tier European-style brands. If you live near a Tomlinsons, you're lucky. MudBay in Seattle has a similar high-end lineup. They offer same-day delivery if you order by 2PM. That's convenient for the city folk.
A few more tips from our experience: if you want the best-rated overall, start with Open Farm. If you want variety, pick Merrick. If you're on a budget, Blue Buffalo Life Protection Formula is a solid choice. Rotate between two or three brands to prevent food sensitivities. And check ingredient lists: the first ingredient should be a named protein like chicken, beef, or salmon, not "poultry meal." We once tried a cheap brand and one of our dogs refused to eat it for two days. Never again.
Look, picking a dog food is personal. What works for our pit mix might not work for your golden. But if you start with Open Farm, you're starting at the top. We've been doing this long enough to know when something is good. And Open Farm is good.
