On the facts printed on its own label, Diamond Naturals Large Breed Adult Dog Chicken and Rice scores 79 out of 100 on our rubric: a solid mid table label. The panel opens with Chicken, and the first ingredient signal earns 20 of its 20 points. At 23% crude protein it ranks 14 of the 19 Diamond Naturals recipes we scored for protein. Crude fat reads 13%.

At 397 kcal a cup it sits mid range for energy, so standard portion maths applies. Its adequacy claim rests on formulation: balanced on paper against the AAFCO nutrient profiles rather than fed to dogs in a trial. The brand carries one FDA posted recall event in our check, set out below with its date.

The panel runs to 61 ingredient lines. 4 of them are animal source lines and 17 are plant lines. The first added fat appears at line 9, so 8 lines sit ahead of it in the recipe by weight. Salt appears at line 15 of 61: ingredients listed after salt are present in small amounts, a standard reading aid for long panels. The vitamin and mineral pack begins around line 39; the 23 lines from there on are mostly supplements, preservatives and functional extras rather than staple foods.

Its closest relative in this brand is Senior Dog Chicken, Egg and Oatmeal, sold as Dry food: the two panels share most of their ingredients. In the first ten, this recipe has grain sorghum, dried yeast, where its relative has oatmeal, dried plain beet pulp. The full comparison is on the relative's own review page.

Ingredient notes: the first ten, one by one

Definitions below are written from AAFCO's ingredient definitions in our own words. They describe what an ingredient is, never what a brand claims about it. Names that appear in our ingredient dictionary link to it; the dictionary counts how many scored recipes carry each ingredient.

  • Owners who want a named whole meat, not a meal or a plant, at the top of the panel

Who should skip it

  • Owners who specifically want a food proven in feeding trials rather than by formulation

The brand's recall record

2012: Diamond Naturals dry dog foods made at the Diamond Pet Foods plant in Gaston, South Carolina (including the Lamb Meal and Rice and Small Breed Lamb and Rice formulas) were recalled in April and May 2012 over possible Salmonella contamination. The FDA posted the recall notices. The same plant event covered several brands made at Gaston in those months; we count it once, as one event, the same way this database counts it for the other Gaston brands.

The single event is from 2012 and sits with the Gaston plant that then made these dry foods. We count it because quality systems belong to the maker, and we date it plainly so readers can weigh its age.

Feeding it

Switch foods gradually over about a week, mixing more of the new food into the old each day. Portion by calories, not by the look of the bowl: our feeding calculator works out a daily amount from your dog's weight, and this recipe's calorie line above is the number it needs.

What that means at the bowl, for a typical neutered adult (resting energy 70 times body weight to the power 0.75, times 1.6; treats come out of the same budget):

Dog's weightDaily energyOf this recipe, at 397 kcal a cup
3 kgabout 255 kcalabout 0.6 cups
10 kgabout 630 kcalabout 1.6 cups
20 kgabout 1,059 kcalabout 2.7 cups
30 kgabout 1,436 kcalabout 3.6 cups

Puppies, pregnant dogs and very active dogs need more; older and weight watching dogs need less. The calculator linked above adjusts for those cases.

Frequently asked questions

What score does Diamond Naturals Large Breed Adult Dog Chicken and Rice get in this review?

Is Diamond Naturals Large Breed Adult Dog Chicken and Rice suitable for puppies?

No: the label is written for adult maintenance, so it is not the food to raise a puppy on. Puppies need a recipe whose adequacy statement covers growth or all life stages.

The FDA posted the recall notices. The same plant event covered several brands made at Gaston in those months; we count it once, as one event, the same way this database counts it for the other Gaston brands. The full record is in the recall section on this page.

No: its panel includes whole grain brown rice, so it is a grain inclusive recipe. The full ingredient list above shows every grain line in label order.

How much Diamond Naturals Large Breed Adult Dog Chicken and Rice should I feed my dog?

Work from calories, not cup habits: a typical neutered adult needs about 70 times body weight to the power 0.75, times 1.6, in kcal a day, and treats come out of the same budget. The feeding section on this page turns that into amounts of this recipe by weight, and our feeding calculator adjusts it for puppies, seniors and weight loss.
