OM Overweight Management Select Blend Chicken Flavor Dry Dog Food, 25-lb bag
Graded by The Sniff System
Purina Pro Plan Veterinary Diets OM Overweight Management Select Blend Chicken Flavor is a dry food formulated for overweight dogs, with whole grain corn as the first ingredient.
This formula has AAFCO feeding trial substantiation, which is a strong indicator of nutritional adequacy. It also uses premium micronutrient forms like chelated minerals, which are more bioavailable.
The formula is plant-protein-dominated, with whole grain corn as the first ingredient, and it lacks a declared omega-3 source. It also contains menadione, a synthetic vitamin K3 banned in human supplements due to toxicity concerns at high doses.
Good fit for adult dogs needing weight management, especially if vet-recommended. Less ideal if you prefer animal-based protein and natural vitamin K.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
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. Strong fit for active large sporting breeds like Labrador Retrievers, Golden Retrievers, and English Setters navigating weight management. At 219 kcal/cup this formula runs on the lean side, with crude fiber at 15% (above the catalog median, supports satiety). 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) .

At 35/100, this formula sits below where we look for everyday picks. The lift comes from AAFCO compliance, worth 8 points to the final number: AAFCO feeding trial substantiation for not stated. Where it lost ground: protein quality, costing 17 points. Plant-protein-dominated formula. whole grain corn as the #1 ingredient. The path to C-tier is about 10 points; protein quality is the structural lever.

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.
- 2protein plantsoybean meal
Concentrated soy protein. Cheap plant protein that pads the label number, common in budget formulas.
Position 2: 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.
- 3soybean germ meal
- 4soybean hulls
- 5soy flour
Refined soy. Cheap plant protein, common in budget formulas. Pads the protein percent without matching meat amino acids.
- 6protein 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 6: supporting protein. Modest contribution to total protein weight.
- 7corn 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 7: supporting grain. Smaller contribution to the carb deck.
- 8fiberpea fiber
Insoluble fiber from peas. Doesn't carry the protein-inflation concern of pea protein. Mostly there for stool quality.
Position 8. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 9othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 10fiberpowdered cellulose
Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.
Position 10: functional fiber for digestion or satiety.
- 11animal fat preserved with mixed-tocopherols
Position 11: trace fat. Below the level that materially shifts the fat profile.
- 12glycerin
Humectant used in soft-moist foods to keep them chewy. Safe in moderation but a signal of a processed semi-moist product.
- 13protein animalchicken
Real meat. Primary protein source, with the amino acid profile dogs actually evolved to eat.
Position 13: trace protein. Likely there for amino-acid diversity or label appeal more than nutritional weight.
- 14malted barley flour
- 15mineraltricalcium phosphate
Calcium and phosphorus source. Same role as dicalcium phosphate, slightly different ratio.
- 16mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 17l-lysine monohydrochloride
Stable form of L-lysine, an essential amino acid. Common in plant-heavy formulas to balance the amino acid profile.
- 18mono and dicalcium phosphate
Source of calcium and phosphorus. Standard inclusion in complete dog foods.
- 19mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 20mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 21vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.
- 22supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 23supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 24mineralmanganese proteinate
Manganese bound to protein for better absorption. The chelated form most premium brands use.
- 25supplementl-carnitine
Amino acid derivative that helps the body convert fat into energy. Common in weight-management formulas.
