DH Dental Health Small Bites Dry Dog Food, 6-lb bag
Graded by The Sniff System
Purina Pro Plan Veterinary Diets DH Dental Health Small Bites Dry Dog Food is a dry formula with chicken as its primary protein source.
It features a strong protein profile, with chicken as the primary ingredient, which means good biological value for your dog. It also includes quality carbohydrate sources that provide fermentable fiber. The formula has AAFCO feeding trial substantiation.
There is no declared omega-3 source, like fish or algae oil, in the ingredient list. The food also contains menadione, a synthetic vitamin K3, which is permitted in pet food but premium brands often use natural alternatives.
Good fit for dogs needing dental health support or preferring small kibble. Less ideal if you prefer natural vitamin K or added omega-3s.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Strong fit for active large sporting breeds, including the Labrador Retriever, navigating weight management. Working in its favor: crude fiber (5%) helps satiety. At 330 kcal/cup this formula runs on the lean side, with crude fiber at 5% (above the catalog median, supports satiety). The landmark 14-year Purina Lifespan Study on 48 Labrador Retrievers demonstrated that dogs fed 25% fewer calories lived a median of 1.8 years longer and delayed the onset of chronic diseases. According to the Association for Pet Obesity Prevention's 2023 survey, 59% of dogs in the United States were classified as overweight or obese by their veterinary healthcare professional, representing an estimated 55 million dogs (APOP, 2023) .

Middle-of-pack grade. 59/100 (C) reflects the structural fit of this formula against The Sniff System's eight scoring components. Protein quality did the heavy lifting (+20.5 points): Strong protein profile with chicken as the primary ingredient, delivering high biological value. What we'd flag for vet discussion: fat quality (-8 points). No declared omega-3 source. Fish oil, salmon oil, and algae oil all absent. B-tier is 1.0 points away. Improving fat quality is the most direct route.

- 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.
- 2protein animalchicken meal
Chicken with the water cooked out. Per pound, packs more protein than fresh chicken. See why →
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3grainrice
Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.
Position 3: major carbohydrate source.
- 4grainyellow corn
Position 4: supporting grain. Smaller contribution to the carb deck.
- 5grainground wheat
Whole wheat. Fine for most dogs, though a portion are sensitive. Not a quality concern, just a fit-for-your-dog question.
Position 5: supporting grain. Smaller contribution to the carb deck.
- 6corn 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 6: supporting grain. Smaller contribution to the carb deck.
- 7animal fat preserved with mixed-tocopherols
Position 7: trace fat. Below the level that materially shifts the fat profile.
- 8fiberdried beet pulp
Soluble fiber from sugar-beet processing. Sometimes treated as a filler, but it's actually one of the better fiber sources in kibble. See why →
Position 8: functional fiber for digestion or satiety.
- 9fiberpowdered cellulose
Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.
Position 9: functional fiber for digestion or satiety.
- 10dried yeast
Natural source of B vitamins and trace minerals. Adds a savory flavor that dogs respond well to.
- 11liver flavor
- 12dried egg product
Whole eggs with the water removed. Same nutritional value as fresh eggs, just shelf-stable.
Position 12: trace protein. Likely there for amino-acid diversity or label appeal more than nutritional weight.
- 13glycerin
Humectant used in soft-moist foods to keep them chewy. Safe in moderation but a signal of a processed semi-moist product.
- 14mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 15mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 16l-lysine monohydrochloride
Stable form of L-lysine, an essential amino acid. Common in plant-heavy formulas to balance the amino acid profile.
- 17mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 18phosphoric acid
- 19vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.
- 20mono and dicalcium phosphate
Source of calcium and phosphorus. Standard inclusion in complete dog foods.
- 21supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 22mineralzinc sulfate
Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.
- 23l-ascorbyl-2-polyphosphate
A stable form of vitamin C used in pet food. Provides antioxidant support and survives processing better than plain ascorbic acid.
- 24vitaminthiamine mononitrate
B vitamin (B1). Essential for nervous system function. Cooked-in vitamin loss is why thiamine is always added back.
- 25mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
