Pros: Third ingredient is a named meat product, grainless.
Cons: Insufficient meat content, use of by-products, other low quality ingredients.

The major ingredient in this food is potato. This takes the form of dehydrated potatoes as the first ingredient, potato protein and potato fiber fifth on the ingredient list. The latter is essentially filler, an insoluable fibre designed to increase bulk, make the dog feel full and aid passage through the intestinal tract. Cellulose powder is further filler, also known as sawdust.

The main nutritional basis of the food comes from duck by-product meal and duck, the second and fourth ingredients. In the latter case, the ingredient is inclusive of water content. Once removed, as it must be to produce a dry product, this ingredient will weigh around 20% of its wet weight and as such is probably more accurately placed further down the ingredient list. It is thus unlikely that this ingredient contributes substantially to the meat content of the food.

Of greater concern is the use of by-products in the food. It is impossible to ascertain the quality of by-products and these are usually products that are of such low quality as to be rejected for use in the human food chain, or else are those parts that have so little value that they cannot be used elsewhere in either the human or pet food industries. We recommend avoiding any pet food using such ingredients. Duck by-products are likely to be similar to chicken by-products, for which the AAFCO definition of meal is “consists of the ground, rendered, clean parts of the carcass of slaughtered chicken, such as necks, feet, undeveloped eggs and intestines, exclusive of feathers, except in such amounts as might occur unavoidable in good processing practice.”

This is a prescription food and better than some of its type. However, we note that there are similar products available without prescription that offer a higher meat content and the use of better quality ingredients (eg. whole potatoes and meat rather than by-products). The nutrient content of this food is near the minimum allowable for adult maintenance (per AAFCO) and below that for puppies.
