Hydrolyzed Protein Loaf Wet Dog Food

Verified Aug 22, 2026

Dog · Wet Adult All Breed Sizes

This is a veterinary therapeutic canned diet for adult dogs that uses hydrolyzed soy protein and hydrolyzed chicken liver, which are broken down into very small pieces to reduce the chance of triggering food reactions. Pea starch provides the main carbohydrate source, while added fiber and fish oil help support digestive function and skin health. It’s designed for dogs who need a hydrolyzed-protein diet under veterinary supervision.

Vet-directed diet

This is a therapeutic diet, formulated for a specific medical condition under veterinary direction. KibbleLab does not assign it a general wellness score, because a therapeutic diet's nutrient targets are set clinically, not by maintenance standards. Your veterinarian selects the right therapeutic diet for your pet.

Nutritional Perspective

KibbleLab Review

Strengths

  • Uses hydrolyzed soy protein and hydrolyzed chicken liver, which are typically well tolerated in dogs with food allergies or protein sensitivities.
  • Complete and balanced to AAFCO standards for adult maintenance, so it can be fed as the sole diet for adult dogs under veterinary guidance.
  • Includes a structured blend of fibers (powdered cellulose, gums) and prebiotic-type ingredients that can help support normal stool quality and digestive health.
  • Contains fish oil, which is a useful source of omega-3 fatty acids that can support skin and coat health in dogs with dermatologic issues.

Considerations

  • Soy is a common allergen for some dogs, so in rare cases even hydrolyzed soy may not be appropriate; this diet should be used only under veterinary guidance, especially for allergy workups.
  • This formula is designed for adult maintenance and is not appropriate as the sole diet for growing puppies or pregnant/lactating dogs.
  • Pea starch is a main carbohydrate source; while this diet is hydrolyzed and prescription-based, owners of dogs with specific concerns about legumes should discuss this choice with their veterinarian.

Top 5 Ingredients Explained

01
Water
Water is an essential nutrient and the primary solvent and moisture component in pet foods, especially wet and canned diets, and is also used in processing and to adjust texture and palatability. It is vital for digestion, nutrient transport, temperature regulation and waste removal in dogs and cats; pets must have constant access to clean water as dehydration can quickly lead to serious health issues and requirements increase with activity, heat, or illness, while moisture in wet food can help meet part of their daily needs.
02
Pea Starch
Pea starch is used in pet foods primarily as a carbohydrate binder, thickener and texture agent to help form kibble and provide readily digestible energy, rather than as a protein or fiber source. It is a gluten‑free, highly digestible starch that can increase calorie density and glycemic load (important for overweight or diabetic pets) and, like other pea/legume ingredients used in high amounts in some grain‑free diets, should be part of a balanced formulation chosen with veterinary guidance for pets with special health concerns.
03
Hydrolyzed Soy Protein
Hydrolyzed soy protein is a processed plant protein broken into small peptides and amino acids and is used in pet foods as a digestible protein source and flavor enhancer, often in hypoallergenic or limited‑ingredient formulations. It can improve digestibility and may reduce allergic reactions for some animals, but it may still trigger soy‑sensitive pets, does not supply certain nutrients cats need from animal proteins (e.g., taurine), and formulations should be evaluated for added sodium or flavoring compounds.
04
Cellulose Powder
Cellulose powder is an insoluble, plant-derived fiber commonly used in pet foods as a bulking agent, binder and calorie-diluting texturizer to help control weight and improve stool formation; it is not digestible by dogs or cats and contributes negligible energy or vitamins. While it can aid stool consistency and manufacturing performance, cellulose is non‑fermentable so offers little prebiotic benefit, and high inclusions can reduce palatability or displace nutrients—formulations, especially for cats with lower fiber tolerance, should be balanced accordingly.
05
Hydrolyzed Chicken Liver
Hydrolyzed chicken liver is enzymatically broken-down chicken liver used in pet foods as a highly palatable, easily digested source of protein, amino acids and liver-derived nutrients (notably vitamin A and B vitamins), and it’s commonly included in hypoallergenic or limited-ingredient diets because hydrolysis reduces the likelihood of an allergic reaction. While it can improve digestibility and flavor and add nutrient density, very sensitive animals may still react to hydrolyzed proteins, and concentrated liver ingredients can contribute excess vitamin A or purines if overused, so follow feeding guidelines and consult your veterinarian for pets with known sensitivities or metabolic concerns.
