HF Hydrolyzed for Food Intolerance Grain-Free Dry Dog Food, 22-lb bag
Graded by The Sniff System
Blue Buffalo Natural Veterinary Diet HF Hydrolyzed for Food Intolerance Grain-Free Dry Dog Food is a grain-free dry formula built around salmon hydrolysate.
This formula includes quality fat sources, like canola oil and flaxseed, and likely contains marine oil for EPA and DHA. It also uses premium micronutrient forms, such as chelated minerals, which are easier for dogs to absorb.
The biggest concern is the absence of an AAFCO statement, which means nutritional completeness is unverified. Also, the primary protein, salmon hydrolysate, is noted for delivering limited bioavailable amino acids.
Good fit for dogs with food intolerances who need a hydrolyzed protein diet. Less ideal if you want verified nutritional completeness.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Good fit for adult Labrador Retrievers navigating weight management. Working in its favor: crude fiber (5%) helps satiety. At 368 kcal/cup this formula runs on the moderate side, with crude fiber at 5% (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) .

Middle-of-pack grade. 51/100 (C) reflects the structural fit of this formula against The Sniff System's eight scoring components. Fat quality did the heavy lifting (+12 points): Quality fat sources: named fat with marine oil (EPA and DHA source). What capped it: the score can't exceed 59 because the AAFCO nutritional adequacy statement isn't disclosed on the retailer page (so our methodology can't verify the formula meets adult, growth, or all-life-stages standards). Removing the cap alone wouldn't change the band. Protein quality is the deeper issue.
Quality fat sources: named fat with marine oil (EPA and DHA source).
Includes egg, named fish, or organ meat for diverse high-bioavailability protein.
Premium micronutrient forms such as chelated minerals or natural vitamin E.
Low protein quality. salmon hydrolysate delivers limited bioavailable amino acids.
No AAFCO statement. Nutritional completeness unverified.

Similar dog foods worth considering
Three lenses on products with formulation profiles similar to this one.
Surfaced from a vector similarity search across 3,491 scored dog foods. How this works.
Read why each ingredient is good or bad for dogs.
- 1salmon hydrolysate
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2pea starch
Refined starch from peas, mostly carbs after the protein is removed. Counts toward the legume stack the FDA examined.
Position 2. Pulse-family ingredient this high in the deck is a notable build choice. When stacked with other pulses in the top 10, matches the formulation pattern the FDA flagged in its diet-associated DCM investigation.
- 3vegetablepotato
Standard white potato. Steady carb source, common starch in grain-free recipes.
Position 3: meaningful whole-food inclusion. Source of vitamins, antioxidants, or natural fiber.
- 4legumepeas
Cheap protein bulk. Fine in small amounts, but when peas stack with lentils and chickpeas in the top ingredients, it's the pattern the FDA flagged in its heart-disease investigation. See why →
Position 4. Within the FDA's top-5 DCM-pattern threshold. Especially notable if multiple pulses stack here.
- 5protein plantpea protein
Concentrated plant protein. Inflates the protein number on the label without matching the amino acid quality of meat.
Position 5. Within the FDA's top-5 DCM-pattern threshold. Especially notable if multiple pulses stack here.
- 6fatcanola oil
Plant oil. Some omega-3 from the parent plant, though dogs absorb it less efficiently than fish-derived omega-3. Fine in moderation.
Position 6: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.
- 7potato starch
Refined potato. Pure carb energy, low on other nutrition. Often used as a binder in grain-free recipes.
- 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.
- 10fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
Position 10: trace fat. Below the level that materially shifts the fat profile.
- 11mineraldicalcium phosphate
Calcium and phosphorus combined. Required source of both minerals, especially in formulas without much bone content.
- 12mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 13fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
Position 13. Trace marine oil. Contributes some omega-3 but well below the level that drives EPA/DHA totals.
- 14vegetablepumpkin
Soluble fiber that supports stool quality. Mild and well-tolerated.
Position 14: garnish-level inclusion. Marketing-prominent but minimal nutritional impact at this position.
- 15supplementdried kelp
Natural source of iodine and trace minerals. A common premium-brand inclusion.
- 16fiberdried chicory root
Natural prebiotic. Feeds beneficial gut bacteria. The same compound (inulin) used in human gut-health products.
- 17mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 18supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 19supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 20mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 21vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.
- 22supplementl-tryptophan
Essential amino acid. Sometimes added in calming or weight-management formulas.
- 23preserved with mixed tocopherols
- 24zinc amino acid chelate
Zinc bound to amino acids for better absorption. Same idea as zinc proteinate, the premium form of the mineral.
- 25l-threonine
Essential amino acid. Sometimes added when plant proteins dominate, since threonine is naturally lower in plants than meat.
