Our take on the Diamond Maintenance Formula Adult Dry Dog Food

Diamond Maintenance Formula is a budget-minded adult dry dog food built on chicken, whole grain corn, wheat and rice, with added omega-3 and omega-6 for skin and coat and a vitamin and mineral blend. It is a maintenance diet for medium dogs, not a performance or life-stage formula, so it suits healthy adult dogs with ordinary needs. Against premium grain-inclusive rivals it offers fewer named meats and no probiotics or glucosamine, but it covers the basics for owners who want a simple everyday kibble. Reviewers generally find it palatable and easy to feed, while some report loose stools or itching in sensitive dogs.

Questions and answers

Is Diamond Maintenance Formula good for dogs with grain allergies?
No. Corn, wheat and rice are core ingredients, so it is a poor choice for dogs with confirmed grain or wheat sensitivity. Look for a grain-free or limited-ingredient formula instead.
Can puppies eat this food?
It is an adult maintenance formula, not a growth diet. Puppies need higher protein, fat and calcium ratios, so choose a puppy or all-life-stages food.
How much should I feed my medium dog?
Follow the bag's weight-based chart and adjust for activity, then check body condition monthly. A medium adult dog typically needs a few cups a day, split into two meals.
Does it help with dry skin and shedding?
It includes omega-3 and omega-6 plus vitamin E, which support skin and coat. Results vary, and dogs with real skin issues may need a vet and a diet with more fish oil.
What is in the bag?
A single 40 lb bag of dry kibble. It is not resealable in most packs, so store it in an airtight container.
How does it compare with Diamond Naturals?
Naturals uses more named meats and no corn or wheat, while Maintenance is the simpler, grain-based line. Maintenance suits budget feeding; Naturals suits owners avoiding grains.
Where is the Diamond Maintenance Formula Adult Dry Dog Food cheapest?
At Chewy, for $37.99, as of our latest check.
