But is it really a solid choice for your furry friend? I get it. You want something that’s good for your dog’s health, doesn’t break the bank, and makes feeding easy with that big bag. So here’s the scoop.
Diamond Naturals nails a combo of wholesome ingredients, probiotics, and superfoods that support digestion, immunity, and even joint health. But like any brand, it’s not without its quirks — things like using “beef meal” instead of fresh beef might have you scratching your head. Stick around and I’ll walk you through everything you need to know before deciding if this brand fits your pup’s needs.
Product Overview
What’s Available in 40 Lbs
First off, the 40-pound bag is available in several popular formulas tailored for different life stages and breed sizes — because one size definitely does not fit all when it comes to dog food. You’ll find:
- Beef Meal & Rice Formula
 - Chicken & Rice (Large Breed)
 - Lamb Meal & Rice Formula (Adult and Large Breed)
 - Salmon-enriched options
 - Large Breed Puppy Formula
 
Each one focuses on a balanced nutrition profile and includes extra bits to support specific needs. By the way, if you want a look at the broader diamond dog food lineup, that’s a good spot to check out.
Why Do People Choose Diamond Naturals?
The brand highlights key perks like guaranteed probiotics, added superfoods such as chia seeds and kale, and targeted nutrients like glucosamine and chondroitin for joint support. Plus, the puppy formulas come with DHA sourced from salmon oil — important stuff for brain and vision development. These aren’t just buzzwords either; probiotics are backed by science to help with gut health and immunity, which can make a real difference for dogs with sensitive stomachs or those prone to allergies.
Big Bags for Big Savings
Having that hefty 40 lb bag around is a blessing — it cuts down trips to the store and usually means better bang for your buck compared to smaller bags. If you’ve got a large dog or even a couple of pups, you’ll appreciate not running out mid-week. Just watch your storage space to keep the kibble fresh.
Inside the Bag: What Are You Feeding Your Dog?
The First Ingredient: Beef Meal Explained
Let’s demystify that “beef meal” label right upfront because I know it can feel a bit confusing. Beef meal isn’t just mystery meat — it’s a concentrated form of beef with moisture removed, so it actually packs nearly three times more protein than fresh beef by weight. That’s the logic behind Diamond Naturals beef meal first ingredient, providing a solid protein punch to fuel your dog’s muscles and energy.
However, it’s worth knowing that beef meal, while protein-rich, can vary in quality depending on how it’s sourced and processed. It’s not the same as fresh or whole meat cuts, but it’s a cost-effective way to offer protein density that many high-end brands also use. So, it’s not a red flag, just something to understand in context.
Protein Variety and Quality
Beyond beef meal, the formulas often include other protein types like pasture-raised lamb, cage-free chicken, fish meal, and even real salmon—which is great for essential Omega-3 fatty acids. These options help round out the amino acid profile your dog needs for overall vitality, coat health, and immune function.
For a closer, ingredient-by-ingredient breakdown, there’s a solid resource on diamond naturals dog food ingredients that dives deep into what each formula really packs.
Superfoods, Probiotics & Omega Power
Superfoods like chia seed, quinoa, spinach, blueberries, and kale aren’t just fancy names. They bring important antioxidants and phytonutrients, which support your pup’s immune system and overall health. Add to this guaranteed probiotics—in every dry formula—that promise billions of beneficial bacteria per pound, and you’ve got digestive support that can reduce tummy troubles and improve nutrient absorption.
And those Omega fatty acids, especially from salmon oil (diamond naturals dog food salmon), work wonders for keeping skin supple and coats shiny. It’s like skincare and brain food, all wrapped up in kibble.
Fiber and Other Additions
Don’t overlook the fiber blend either — pumpkin, dried kelp, and chicory root all join forces to keep digestion moving smoothly. Plus, glucosamine and chondroitin supplements make certain formulas ideal for large or senior dogs needing extra joint support.
Choosing the Right Formula
Puppy Needs — Big and Growing
If you’re raising a large breed puppy, getting the formula right is crucial. Diamond Naturals’ large breed puppy recipe balances calcium and phosphorus carefully to support healthy bone and joint development without risking growth issues.
And bonus: the large breed puppy formula includes DHA for brain and vision development, a nutrient that’s often overlooked in less specialized brands. It really shows the company’s expertise in targeting different life stages with tailor-made formulas.
Adult Dogs and Large Breeds
Adult and large-breed formulas focus on sustained energy, muscle maintenance, and joint health with added glucosamine and chondroitin. Plus, they typically have kibble sized just right for bigger jaws, which is a nice touch to keep mealtime enjoyable.
Senior or Special Needs Considerations
While Diamond Naturals doesn’t have a specific senior formula in the 40 lb size, their adult formulas can fit into weight management or less active life stages if portioned carefully and paired with vet advice. For dogs with allergies or sensitivities, it’s always smart to check ingredient lists carefully and do a slow transition.

How Much to Feed?
Feeding depends on your dog’s weight, activity, age, and metabolism, naturally. Here’s a rough guide:
- Small dogs (up to 20 lbs): ~½ to 1½ cups/day
 - Medium dogs (20-50 lbs): 1½ to 3 cups/day
 - Large dogs (50-90 lbs): 3 to 5 cups/day

If you’ve got a rambunctious large breed, you might need to lean toward the higher end. Always check the packaging for specific feeding guides and adjust based on your dog’s condition and response.
