Adult Small Breed Chicken & Rice Formula Dry Dog Food, 18-lb bag
Graded by The Sniff System
Purina Pro Plan Adult Small Breed Chicken & Rice Formula is a dry food for adult dogs, with chicken as its primary protein source.
Chicken as the first ingredient provides good amino acid coverage. The formula also includes dried egg product and fish meal, which add diverse, highly bioavailable protein sources.
A significant watch item is the lack of an AAFCO statement, meaning its nutritional completeness is unverified. Also, there's no declared source of omega-3 fatty acids.
Good fit for adult small breed dogs. Less ideal if you prioritize an AAFCO statement or a declared omega-3 source.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Strong fit for moderately active toy breeds, including the Cavalier King Charles Spaniel, navigating diet-associated DCM concerns. Chicken anchors position 1, with zero pulses in the top 15, plus fish meal at position 8. The FDA's 2019 investigation update on diet-associated DCM included 13 reported cases in Cavalier King Charles Spaniels, making them one of the top 15 most frequently reported breeds at that time (FDA, 2019) .

Sniff scored this formula 48/100, landing in C-tier (acceptable-with-notes). The biggest contributor was protein quality (+15 points): Reasonable protein quality. chicken delivers solid amino acid coverage. A hard cap of 59 also applied because the AAFCO nutritional adequacy statement isn't disclosed on the retailer page (so our methodology can't verify the formula meets adult, growth, or all-life-stages standards). Even without the cap, the base component scores sit below the next band. The structural fix would need to address fat quality as well.
Reasonable protein quality. chicken delivers solid amino acid coverage.
Includes egg, named fish, or organ meat for diverse high-bioavailability protein.
No declared omega-3 source. Fish oil, salmon oil, and algae oil all absent.
No AAFCO statement. Nutritional completeness unverified.
- Lowest fat quality in Purina Pro Plan's lineup (4/16)

Read why each ingredient is good or bad for dogs.
- 1protein animalchicken
Real meat. Primary protein source, with the amino acid profile dogs actually evolved to eat.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2grainrice
Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.
Position 2: major carbohydrate source.
- 3corn protein meal
Concentrated corn protein. Similar in role to corn gluten meal, pads the protein number on the label without matching meat amino acids.
Position 3: major carbohydrate source.
- 4protein animalpoultry by-product meal
Unnamed poultry. The mix can include any combination of chicken, turkey, or other birds, with no traceability. Named by-product meals are fine. This one isn't.
Position 4: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 5grainwhole grain corn
Whole corn with the kernel intact. Decent fiber and B vitamins, though it can crowd out meat in cheaper recipes.
Position 5: supporting grain. Smaller contribution to the carb deck.
- 6beef fat preserved with mixed-tocopherols
Real animal fat from a named species, with natural vitamin E doing the preservation. The clean version.
Position 6: supporting protein. Modest contribution to total protein weight.
- 7corn germ meal
Position 7: supporting grain. Smaller contribution to the carb deck.
- 8protein animalfish meal
Concentrated fish protein, usually whitefish, herring, or mackerel. Strong amino acid profile. See why →
Position 8: supporting protein. Modest contribution to total protein weight.
- 9dried egg product
Whole eggs with the water removed. Same nutritional value as fresh eggs, just shelf-stable.
Position 9: supporting protein. Modest contribution to total protein weight.
- 10othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 11wheat bran
Position 11: minor grain inclusion.
- 12mono and dicalcium phosphate
Source of calcium and phosphorus. Standard inclusion in complete dog foods.
- 13mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 14l-lysine monohydrochloride
Stable form of L-lysine, an essential amino acid. Common in plant-heavy formulas to balance the amino acid profile.
- 15mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 16mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 17supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 18mineralzinc sulfate
Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.
- 19mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 20mineralmanganese sulfate
Inorganic manganese. Functional but less well-absorbed than the chelated proteinate form.
- 21mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
- 22mineralcalcium iodate
Source of iodine for thyroid function. Functional, required in complete formulas.
- 23mineralsodium selenite Flagged
Inorganic selenium. Effective at AAFCO levels, no documented safety concern in dogs despite what some pet food blogs claim. Selenium yeast is a marginal upgrade, not a necessity. See why →
- 24l-ascorbyl-2-polyphosphate
A stable form of vitamin C used in pet food. Provides antioxidant support and survives processing better than plain ascorbic acid.
- 25probioticdried bacillus coagulans fermentation product
Probiotic strain. More heat-stable than lactobacillus, which means more of it likely survives kibble processing.
