Veterinary Diets HA Hydrolyzed Protein Chicken Formula Dry Dog Food
Verified Aug 13, 2026
This is a veterinary therapeutic dry food designed for adult dogs who need a hydrolyzed protein diet, often due to suspected food allergies or chronic digestive issues. It uses hydrolyzed soy as the main protein source, with corn starch as the single carbohydrate source, and includes hydrolyzed chicken organ meats for flavor and added nutrients. The formula is complete and balanced for adult maintenance and is meant to be used under veterinary supervision.

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.

Where these benefits come from
Benefits the manufacturer highlights in its own product marketing. KibbleLab lists them for reference and does not verify these claims.KibbleLab Review
Strengths
- Uses hydrolyzed protein, which is broken into smaller pieces and is less likely to trigger food reactions in sensitive dogs.
- Provides a single main carbohydrate source, which helps simplify the diet when you’re tracking food triggers.
- Is complete and balanced to meet AAFCO nutrient profiles for adult maintenance, so it can be used as the main diet.
- Includes added taurine, essential amino acids, and vitamins and minerals to support overall health while on a restricted diet.
Considerations
- Primary protein is hydrolyzed soy, so this may not suit dogs that must avoid soy entirely.
- Protein level is on the lower side compared with many standard adult dog foods, which may not be ideal for very active or working dogs.
- This is a therapeutic diet intended for specific medical situations, so it should be used only under veterinary guidance.
- Contains hydrolyzed chicken liver and giblets, so it is not appropriate if your dog must strictly avoid all chicken-derived ingredients.

Top 5 Ingredients Explained
01
Corn Starch
Corn starch is a concentrated carbohydrate used in pet foods primarily as a thickener, binder and texture enhancer for kibbles, treats and canned gravies. It supplies digestible calories with minimal protein or micronutrients, so while generally safe for most dogs and cats it can contribute to excess calories and blood‑sugar increases in overweight or diabetic pets and may be a concern for animals with grain sensitivities.
02
Soy Protein
Soy protein is a concentrated plant-based protein commonly used in pet foods to boost protein content, improve texture and binding, and provide a cost-effective alternative to animal proteins. It supplies substantial protein for dogs and can be used in cat diets when formulas are properly balanced, but its amino-acid profile and digestibility are generally lower than animal proteins (often requiring supplementation such as taurine for cats), and some pets may have soy sensitivities or be affected by soy compounds, so diets with soy should be formulated and processed appropriately.
03
Canola Oil
Canola oil is used in pet foods as a concentrated fat source and palatability enhancer that supplies energy and essential fatty acids—mainly omega‑6 (linoleic acid) and some omega‑3 (ALA)—and aids absorption of fat‑soluble vitamins. It can support skin and coat condition when balanced with animal fats or supplemental omega‑3s, but is calorie‑dense so must be portioned to avoid weight gain, does not provide species‑specific fats such as arachidonic acid for cats, and must be kept fresh to prevent oxidation.
04
TBHQ
TBHQ (tertiary butylhydroquinone) is a synthetic antioxidant used in pet foods to stabilize fats and oils and extend shelf life by preventing rancidity. It has no nutritional value; regulatory agencies permit its use at low levels in dog and cat foods, but high doses can be harmful and some pet owners prefer to avoid synthetic preservatives.
05
Coconut Oil
Coconut oil is used as a concentrated fat source and palatability enhancer in dog and cat diets, providing medium-chain triglycerides (notably lauric acid) that can be rapidly metabolized for energy and may help support skin and coat condition. Because it is high in saturated fat and calories, coconut oil should be used sparingly and introduced gradually to avoid gastrointestinal upset, and pets with obesity or a history of pancreatitis should only use it under veterinary guidance.
