OM Metabolic Response Plus Joint Mobility Dry Dog Food, 24-lb bag
Graded by The Sniff System
Purina Pro Plan Veterinary Diets OM Metabolic Response Plus Joint Mobility is a dry veterinary diet that lists fish as a primary protein source.
This formula offers reasonable protein quality, with wheat gluten contributing solid amino acid coverage. It also includes quality fat sources, notably named fat with marine oil, which provides beneficial EPA and DHA. The product has AAFCO feeding trial substantiation.
A key ingredient to note is menadione, a synthetic vitamin K3. It's banned in human supplements due to toxicity concerns at high doses, though permitted in pet food.
Good fit for dogs needing a veterinary diet for metabolic and joint support. Less ideal if you prefer to avoid synthetic vitamin K3.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Strong fit for adult Labrador Retrievers and similar active sporting breeds navigating weight management. Working in its favor: crude fiber (9%) helps satiety. At 285 kcal/cup this formula runs on the lean side, with crude fiber at 9% (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. The 2014 AAHA Weight Management Guidelines define overweight as a Body Condition Score (BCS) of 6-7 on a 9-point scale. A score of 8 or 9 indicates obesity, representing 20-30% and >30% above ideal body weight, respectively (Brooks et al., 2014) .

Middle-of-pack grade. 51/100 (C) reflects the structural fit of this formula against The Sniff System's eight scoring components. Protein quality did the heavy lifting (+15 points): Reasonable protein quality. wheat gluten delivers solid amino acid coverage. What we'd flag for vet discussion: controversial-ingredient penalty (-5 points). Contains menadione. Banned for human OTC use but tolerated at AAFCO-permitted levels in pet food. The only AAFCO-permitted vitamin K source. B-tier is 9 points up. Controversial-ingredient penalty is where to find them.

Read why each ingredient is good or bad for dogs.
- 1protein plantwheat gluten
Concentrated wheat protein. Like other plant gluten meals, it pads the protein number on the label without contributing meat-quality amino acids.
Position 1: plant protein in the top 5. Stacked with animal protein, can inflate the crude protein number without matching the amino-acid quality of named animal sources.
- 2soy protein concentrate
- 3protein 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 3: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 4soybean germ meal
- 5protein animalfish meal
Concentrated fish protein, usually whitefish, herring, or mackerel. Strong amino acid profile. See why →
Position 5: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 6protein plantpea protein
Concentrated plant protein. Inflates the protein number on the label without matching the amino acid quality of meat.
Position 6. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 7corn starch
Position 7: supporting grain. Smaller contribution to the carb deck.
- 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.
- 10othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 11fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
Position 11. Moderate marine-oil inclusion. Supplements EPA/DHA without being the primary fat.
- 12animal fat preserved with mixed-tocopherols
Position 12: trace fat. Below the level that materially shifts the fat profile.
- 13sodium caseinate
- 14dried egg product
Whole eggs with the water removed. Same nutritional value as fresh eggs, just shelf-stable.
Position 14: trace protein. Likely there for amino-acid diversity or label appeal more than nutritional weight.
- 15gelatin
- 16mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 17soy protein isolate
- 18mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 19fiberinulin
Prebiotic fiber that feeds beneficial gut bacteria. Same compound found in chicory root.
- 20mineraltricalcium phosphate
Calcium and phosphorus source. Same role as dicalcium phosphate, slightly different ratio.
- 21mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 22vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.
- 23supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 24supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 25supplementl-carnitine
Amino acid derivative that helps the body convert fat into energy. Common in weight-management formulas.
