The best Diamond dog food for most owners is Diamond Naturals because it offers above-average protein, decent ingredients like brown rice and barley, and a solid reputation from a family-owned company that's been around since 1970. As of early 2025, I stand by this recommendation after testing multiple formulas with my own dog and reviewing customer feedback across major retailers.
I've been reviewing dog food for years, and Diamond is polarizing. People either love it or had a scary experience. The truth is somewhere in the middle. Diamond Pet Foods has made kibble since 1970, and they also produce the higher-end Taste of the Wild line. So they know what they're doing. But not every bag is created equal.
If you're shopping on a budget - and who isn't these days - Diamond Naturals is where you want to land. The standard Diamond dog food is cheaper, yes. But it's grain-inclusive with corn and wheat. I'd skip it unless you're really pinching pennies. The Naturals line uses brown rice and barley instead of cheap fillers. That's a big upgrade. Chewy customers rate Diamond Naturals 4.5 out of 5 stars, with 93% saying they'd recommend it. That's a lot of happy dogs. In our testing, we found that Diamond Naturals consistently produced firm stools and healthy coats across multiple breeds, including my own Labrador mix.
One of the most transparent things about Diamond Naturals is they actually tell you the percentages of key ingredients. The All Life Stage Chicken & Rice formula has 16% chicken, 16% chicken meal, and 16% whole grain brown rice. That adds up to 32% chicken ingredients. Plus chicken fat. The total animal ingredients sit around 48%. That's decent for a mid-priced kibble. Protein hits 26%, which is above average. Fat is 16% - also respectable. According to AAFCO nutrient profiles, these levels are suitable for all life stages, which Diamond Naturals explicitly states on its packaging. This is not a high-performance food for working dogs, but for your average family pet, it's more than enough.

Now, if you've got a puppy, Diamond makes a Premium Puppy formula. It's high in protein at 31% and includes DHA for brain and vision development. One Amazon reviewer mentioned using it for their Golden Retriever and noticed the gas problem got better. If you've ever owned a Golden, you know that's a win. The Diamond Naturals All Life Stage formula also works for puppies, but the Premium Puppy is the one I'd pick for a growing dog.

I see a lot of owners asking about Diamond for dogs with sensitive stomachs or skin allergies. The Facebook group Healthy Thin Dogs has real owners chiming in. One user said their poodle did better on Diamond Naturals Beef Meal and Rice than on Purina One - better stools, better coat, better muscle tone. But another vet tech warned against downgrading from Purina Pro Plan to Diamond because Pro Plan has way more research behind it. Fair point. If you want a brand with decades of clinical feeding trials, Purina Pro Plan or Hill's Science Diet are safer bets. But if you're coming from something like Purina One or Iams and want a step up without spending twice as much, Diamond Naturals is a solid move. If you're feeding Taste of the Wild and need to cut costs, Diamond Naturals is a reasonable downgrade - same parent company, slightly cheaper ingredients. If you're dealing with sensitive tummies or allergies, the best dog food for allergies and sensitive stomachs guide covers both budget and premium options, including limited ingredient diets.
Here's the thing. Diamond has had recalls. More than some boutique brands. But so has Blue Buffalo, so has Purina. Every big brand has had issues. According to the FDA's recall database, Diamond's recalls have primarily been due to potential salmonella contamination, but they've since implemented new safety protocols in their Missouri, California, and South Carolina facilities. The key is that Diamond's manufacturing facilities in the US are inspected regularly, and they've made changes since their last recall. Some owners on RateItAll report inconsistent stools. A few mention horrible gas or bad breath. But plenty of others say their dogs thrive on it. One user with 20 dogs over 15 years reports zero issues. That's a lot of data points.
If your dog has severe allergies or grain sensitivities, look at the Diamond Naturals Grain-Free line or even the Diamond Care vet-formulated recipes. Those are designed for specific health issues. But if you need a limited ingredient diet for confirmed food allergies, look elsewhere. The standard Diamond is not it.
If I were buying Diamond today, I'd pick Diamond Naturals All Life Stage Chicken & Rice. Transition slowly over 7 days. Watch for stool changes. If things look good after two weeks, you're golden. You can also use Diamond Naturals as a base and mix in fresh raw meat or organs. That's what I do for my own dog. Keeps the kibble cost down and gives them more animal protein. I've noticed better coat shine and less shedding since I started doing that. My vet approved, too.
You can find Diamond dog food at Chewy, Amazon, Petbarn in Australia, and some independent pet stores. Availability varies by region. But if you're on a budget and want something better than the cheapest grocery store brands, Diamond Naturals is a solid pick. Just don't expect boutique-level ingredients or decades of feeding trials. It's a middle-of-the-road option that works for most dogs.
For this review, I evaluated ingredient labels, customer ratings from Chewy and Amazon, recall history from the FDA, and firsthand experience feeding Diamond Naturals to my own dog. Below are answers to common questions about Diamond dog food.
