Adult Perfect Weight Management & Joint Support Hearty Vegetables & Tuna Stew Wet Dog Food, 12.5-oz can, 12 count
Graded by The Sniff System
Hill's Science Diet Adult Perfect Weight Management & Joint Support Hearty Vegetables & Tuna Stew is a wet food for adult dogs, primarily featuring pork liver.
This formula uses pork liver, which provides good amino acid coverage for protein quality. It also includes quality fat sources with marine oil, offering beneficial EPA and DHA. The food has AAFCO feeding trial substantiation for adult maintenance.
The score is capped due to relatively low protein and fat content on a dry matter basis. It also contains menadione, a synthetic vitamin K3, and guar gum, an emulsifier with emerging microbiome data.
Good fit for adult dogs needing weight management. Less ideal if you prefer foods without synthetic vitamin K3 or lower protein content.
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. Good fit for active large sporting breeds, including the Labrador Retriever, navigating weight management. Caloric density is not declared, with crude fiber at 5% (above the catalog median, supports satiety), and the product name signals a weight-management design. 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) .

At 46/100, this formula lands mid-pack. The lift comes from protein quality, worth 15 points to the final number: Reasonable protein quality. pork liver delivers solid amino acid coverage. The ceiling on this score is 49, set because the guaranteed analysis falls below AAFCO's minimum nutrient profile. The fix path: a formula update that meets AAFCO minimums. That would lift the cap and put this formula above the B-band line at 60.

Controversial ingredients · 1
- menadioneSynthetic vitamin K3. Banned in human supplements due to toxicity concerns at high doses. Permitted in pet food but premium brands use natural vitamin K alternatives.
Every flagged ingredient has a published basis (confirmed harm / regulatory action / precautionary). See methodology →
Wet and fresh foods contain more water than kibble (typically 65-78%). On a dry-matter basis, this food's protein content is roughly 21%, comparable to premium kibble (typically 30-45% DMB protein).
Read why each ingredient is good or bad for dogs.
- 1chicken broth
Real broth, adds flavor and moisture. Negligible nutrition on its own but tells you the recipe leans on real meat.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2protein animalpork liver
Organ meat. Dense in B vitamins, iron, and vitamin A. Among the most nutritious ingredients on any label.
Position 2. Named organ meat this high is a strong build choice. Concentrated source of taurine, glutamine, and B-vitamins.
- 3vegetablecarrots
Real vegetable. Fiber, beta-carotene, and a small amount of antioxidant value.
Position 3: meaningful whole-food inclusion. Source of vitamins, antioxidants, or natural fiber.
- 4fiberpowdered cellulose
Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.
Position 4: functional fiber for digestion or satiety.
- 5corn starch
Position 5: supporting grain. Smaller contribution to the carb deck.
- 6legumegreen peas
Same as peas. Useful in small amounts. The concern is when pulses dominate the top of the ingredient list. See why →
Position 6. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 7tuna
Position 7: supporting protein. Modest contribution to total protein weight.
- 8protein 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 8: moderate plant-protein boost. Less likely to materially shift the protein profile.
- 9dried tomato pomace
The fiber-rich byproduct of tomato processing. Sometimes flagged unfairly. It's a real fiber source, not a filler shortcut.
Position 9: functional fiber for digestion or satiety.
- 10soybean oil
Plant oil. High in omega-6, which is required but commonly oversupplied. Fine in moderation.
Position 10: trace fat. Below the level that materially shifts the fat profile.
- 11hydrolyzed chicken flavor
Hydrolyzed chicken used as a palatability enhancer. Real ingredient, tiny inclusion, no quality signal either way.
- 12chicken liver flavor
Hydrolyzed chicken liver used as a flavor enhancer. Real ingredient, used in tiny amounts for palatability.
Position 12. Small organ inclusion. Functional but not a primary contributor to the protein profile.
- 13grainrice
Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.
Position 13: minor grain inclusion.
- 14potassium alginate
- 15fatcoconut oil
Saturated fat with medium-chain triglycerides. Mostly marketing in the doses kibble uses, but harmless.
Position 15: trace fat. Below the level that materially shifts the fat profile.
- 16fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
- 17fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
- 18calcium chloride
- 19fiberguar gum
Thickener common in wet food. Emerging research on emulsifiers and the gut microbiome, but no smoking gun in dogs yet. See why →
- 20mineraldicalcium phosphate
Calcium and phosphorus combined. Required source of both minerals, especially in formulas without much bone content.
- 21mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 22calcium lactate
Calcium source from lactic acid fermentation. Functional, well-tolerated.
- 23calcium gluconate
- 24monosodium phosphate
Mineral source and preservative. Standard inclusion at small doses.
- 25vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.
