OM Overweight Management Dry Dog Food, 25-lb bag
Graded by The Sniff System
Purina Pro Plan Veterinary Diets OM Overweight Management Dry Dog Food is a dry formula designed for weight management, with a plant-protein-dominated ingredient list.
This formula has undergone AAFCO feeding trials, which means its nutritional adequacy has been tested in real dogs, not just calculated on paper.
This formula is heavily reliant on plant proteins, with whole grain corn as the first ingredient, and lacks a declared omega-3 source. It also contains menadione, a synthetic vitamin K3, which is flagged due to toxicity concerns.
Good fit for dogs needing a veterinary diet for weight management. Less ideal if you prefer animal-protein-first formulas or want to avoid synthetic vitamin K.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Strong fit for adult Labrador Retrievers navigating weight management. Working in its favor: crude fiber (16%) helps satiety. At 260 kcal/cup this formula runs on the lean side, with crude fiber at 16% (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) .

Read why each ingredient is good or bad for dogs.
- 1grainwhole grain corn
Whole corn with the kernel intact. Decent fiber and B vitamins, though it can crowd out meat in cheaper recipes.
Position 1 grain: primary carbohydrate base. This is a grain-inclusive formula with whole grain corn as the dominant carb.
- 2corn 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 2: major carbohydrate source.
- 3soybean hulls
- 4soybean germ meal
- 5protein plantsoybean meal
Concentrated soy protein. Cheap plant protein that pads the label number, common in budget formulas.
Position 5: 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.
- 6fiberpea fiber
Insoluble fiber from peas. Doesn't carry the protein-inflation concern of pea protein. Mostly there for stool quality.
Position 6. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 7protein 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 7: moderate plant-protein boost. Less likely to materially shift the protein profile.
- 8protein 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 8: supporting protein. Modest contribution to total protein weight.
- 9glycerin
Humectant used in soft-moist foods to keep them chewy. Safe in moderation but a signal of a processed semi-moist product.
- 10othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 11fiberpowdered cellulose
Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.
Position 11: trace fiber inclusion.
- 12animal fat preserved with mixed-tocopherols
Position 12: trace fat. Below the level that materially shifts the fat profile.
- 13mineraltricalcium phosphate
Calcium and phosphorus source. Same role as dicalcium phosphate, slightly different ratio.
- 14mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 15mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 16supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 17vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.
- 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.
- 20l-lysine monohydrochloride
Stable form of L-lysine, an essential amino acid. Common in plant-heavy formulas to balance the amino acid profile.
- 21supplementl-carnitine
Amino acid derivative that helps the body convert fat into energy. Common in weight-management formulas.
- 22mineralmanganese sulfate
Inorganic manganese. Functional but less well-absorbed than the chelated proteinate form.
- 23vitaminniacin supplement
B vitamin (B3). Required in complete dog foods, added as a supplement to standardize the dose.
- 24vitaminvitamin a supplement
Vitamin A in stable, standardized form. Required for vision, immune function, and growth.
- 25soybean oil
Plant oil. High in omega-6, which is required but commonly oversupplied. Fine in moderation.
