l/d Liver Care Chicken Flavor Dry Dog Food, 17.6-lb bag
Graded by The Sniff System
Hill's Prescription Diet l/d Liver Care Chicken Flavor Dry Dog Food is a dry formula with chicken and egg product as its main protein sources.
This formula includes quality carbohydrate sources that provide fermentable fiber, which is good for gut health. It also features quality fat sources, like named fats and marine oil, which supply beneficial EPA and DHA. The product has AAFCO feeding trial substantiation.
The score for this product is capped at 49, mainly because of its relatively low protein content at 16.1% dry matter and high fat content at 21.1% dry matter.
Good fit for dogs requiring a specialized diet for liver care, as prescribed by a veterinarian. Less ideal for healthy dogs without specific dietary needs.
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 adult Labrador Retrievers navigating weight management. Caloric density is not declared, with crude fiber at 6% (above the catalog median, supports satiety). 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 49/100, this formula lands mid-pack. The lift comes from carbohydrate quality, worth 13 points to the final number: Quality carbohydrate sources with fermentable fiber. 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.
Quality carbohydrate sources with fermentable fiber.
Quality fat sources: named fat with marine oil (EPA and DHA source).

Read why each ingredient is good or bad for dogs.
- 1brewers rice
Broken rice kernels left over from milling, usually destined for human beer-making. Cheaper than whole or even white rice. Same carbs, less nutrition than the brown version. See why →
Position 1 grain: primary carbohydrate base. This is a grain-inclusive formula with brewers rice as the dominant carb.
- 2protein animalchicken
Real meat. Primary protein source, with the amino acid profile dogs actually evolved to eat.
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 3: primary fat source. Drives the formula's caloric density and omega-6 content.
- 4protein animalegg product
Processed whole eggs. Same nutritional profile as fresh eggs, just shelf-stable.
Position 4: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 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.
- 6fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
Position 6: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.
- 7fiberpowdered cellulose
Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.
Position 7: functional fiber for digestion or satiety.
- 8chicken liver flavor
Hydrolyzed chicken liver used as a flavor enhancer. Real ingredient, used in tiny amounts for palatability.
Position 8. Functional organ inclusion. Adds amino acids and micronutrients even at smaller weight.
- 9mineraldicalcium phosphate
Calcium and phosphorus combined. Required source of both minerals, especially in formulas without much bone content.
- 10lactic acid
Natural acid used as a mild preservative and pH adjuster. Found in fermented foods too. Safe at typical inclusion.
- 11soybean oil
Plant oil. High in omega-6, which is required but commonly oversupplied. Fine in moderation.
Position 11: trace fat. Below the level that materially shifts the fat profile.
- 12mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 13fiberdried 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 13: trace fiber inclusion.
- 14glyceryl monostearate
- 15mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 16supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 17fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
- 18supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 19mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 20supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 21supplementl-arginine
- 22supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 23zinc oxide
Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.
- 24manganous oxide
Inorganic manganese. Functional, cheaper than chelated forms, less efficiently absorbed.
- 25mineralcalcium iodate
Source of iodine for thyroid function. Functional, required in complete formulas.
