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.

Strengths
- Uses fish meal and potato as the primary protein and carbohydrate sources, which can be useful for dogs needing an alternative to common allergens like chicken or beef.
- Complete and balanced for adult maintenance according to AAFCO, so it can be used as the main diet for adult dogs under veterinary guidance.
- Includes omega-3 fatty acids, including EPA and DHA, which can support skin, coat, and overall inflammation control.
- Formulated specifically for large dogs, with added glucosamine and chondroitin to help support joint health in bigger, heavier-breed dogs.
Considerations
- Protein level (19% as-fed) is on the moderate side, which is usually fine for adult maintenance but may be lower than ideal for very athletic or working dogs unless your vet feels it’s appropriate.
- Fish is a common allergen for some dogs, so this diet would not be suitable if your dog is known to react to fish.
- Because this is a prescription-style formula aimed at specific health needs, it’s best used under veterinary supervision rather than as a casual rotation diet.

Top 5 Ingredients Explained
01
Potato
Potato is commonly used in pet foods as a digestible carbohydrate source and functional binder, supplying starch, fiber, and modest amounts of vitamins (B6, C) and potassium—often included as cooked or dehydrated flakes, starch, or protein concentrates. While it provides energy and helps formulate grain‑free recipes, potatoes are not a primary protein for dogs or cats (and are not nutritionally required for obligate‑carnivore cats), can contribute to excess calories or affect blood glucose in diabetic animals, and must be cooked and free of green skins or sprouts to avoid solanine toxicity; allergies are uncommon but possible.

02
Fish
Fish is commonly used in pet foods as a highly digestible animal protein and an excellent source of omega‑3 fatty acids (EPA and DHA) that support skin and coat health, joint function, and cognitive development in both dogs and cats. It also supplies B vitamins and minerals but can be a common allergen, may contain environmental contaminants or mercury depending on species and sourcing, and raw fish can contain thiaminase—so choose properly processed, nutritionally balanced, and sustainably sourced fish ingredients.
03
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.
04
Potato Protein
Potato protein is a concentrated plant-based protein used in pet foods as a protein source, binder and texture enhancer, offering a highly digestible amino acid profile with relatively good lysine content compared with other plant proteins. It can be a useful hypoallergenic alternative for dogs and a supplement in balanced formulas, but it should not be the sole protein for obligate carnivores like cats because it lacks certain nutrients (e.g., sufficient taurine and other animal-derived factors) and must be used within complete, nutritionally formulated diets; quality processing also minimizes potato-specific compounds such as glycoalkaloids.
05
Natural Flavor
Natural flavor is used primarily as a palatability enhancer in pet foods to improve taste and aroma and is not intended to provide significant nutrients, typically coming from concentrated extracts of meat, poultry, plant, or fermentation sources. While it can increase acceptance in picky dogs and cats, manufacturers are not required to disclose specific sources so pets with known sensitivities or allergies may react, and presence of natural flavor should not be taken as a guarantee of overall product quality.
