Animal feeding tests using AAFCO procedures substantiate that Hill's Science Diet Puppy Large Breed Lamb Meal and Rice Recipe provides complete and balanced nutrition for growing puppies.

Ingredient Review

We'll begin this review of Hill's Science Diet Puppy Large Breed Lamb Meal and Rice Recipe with a detailed discussion of the ingredients.

The first ingredient is lamb meal. Lamb meal is produced by cooking lamb using a process called rendering. The rendering process dramatically reduces the natural moisture of lamb and thereby results in a highly condensed protein source.

The second ingredient is brewers rice. Brewer's rice is the small fragments of rice kernel that are separated from the larger kernels of milled rice. The fragments do not contain the same nutrition profile of the whole kernel and therefore brewer's rice is a lower quality grain. Brewer's rice is typically regarded as an inexpensive and low quality filler.

The third ingredient is whole grain wheat. Whole grain wheat contains the entire grain of wheat (the germ, bran, and endosperm). Wheat is the second most-produced cereal grain in the world (corn is the first). Although wheat is a controversial ingredient, it is not necessarily undesirable because it provides dietary fiber and many other nutrients. However, wheat contains a notable amount of plant based protein, which is inferior to meat based protein and therefore an undesirable substitution.

Wheat is also one of the most common ingredients to cause food allergies or intolerance. However, grains such as wheat are typically low offenders in comparison to certain protein sources (such as beef).

The fourth ingredient is whole grain sorghum. Whole grain sorghum is a gluten-free carbohydrate source. This cereal grain also provides a modest amount of B vitamins and minerals such as magnesium, iron, phosphorus, and manganese.

The fifth ingredient is corn gluten meal. Corn gluten meal is a by-product from the production of various corn products (corn starch, corn syrup, etc). It's very high in protein (nearly 60% protein) and therefore can significant boost the protein content of the product. Because plant based proteins such as corn gluten meal are inferior to meat based proteins (lack many essential amino acids), they are not suitable substitutes.

Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Hill's Science Diet Puppy Large Breed Lamb Meal and Rice Recipe are not as important as the first five ingredients.

However, collectively they still have a significant impact on the overall quality of the product. Therefore, we'll continue discussing the remaining ingredients in this Hill's Science Diet recipe.

Next we have brown rice. Brown rice is naturally rich in fiber and various minerals including manganese, phosphorus, and magnesium. Relative to other grains, brown rice is easy to digest.

The next ingredient is egg product. Egg product consists of shell-free eggs which are easy to digest and contain high quality protein. Egg protein is often given the highest biological value (BV). The BV metric measures the usability of the ingredient's protein.

Then we have pork fat. Pork fat is typically collected while cooking pork using a process called rendering. Pork fat is a relatively high quality source of essential fatty acids. In particular, pork fat is high in linoleic acid, an important omega-6 fatty acid.

Moving on, we have flaxseed. Flaxseeds are an outstanding source of omega-3 fatty acids and dietary fiber. They also provide a notable amount of protein, B vitamins, and various minerals.

Moving on with this review, we have natural chicken liver flavor. As the name implies, natural chicken liver flavor provides chicken liver flavor to the product. This particular flavor is derived from natural sources which may or may not include real chicken liver.

The next ingredient in this review is natural pork flavor. As the name implies, natural pork flavor provides pork flavor to the product. This particular flavor is derived from natural sources which may or may not include real pork.

Our next ingredient is fish oil. Fish oil is defined by AAFCO as "the oil from rendering whole fish or cannery waste." It is typically rich in omega-3 fatty acids and therefore a good fat source. However, the specific fish used to obtain the oil is not specified and therefore we cannot make any specific claims.

lactic acid is the next ingredient in this recipe, which is an organic compound. Lactic acid is most likely used in this recipe as a preservative.

Next on the list is potassium chloride, which is a potassium supplement.

The next ingredient in this recipe is dried beet pulp. Dried beet pulp is the by-product which remains once sugar has been extracted from sugar beets. The primary contribution of beet pulp is dietary fiber.

We'd also like to note that beet pulp is fairly controversial in pet food. Proponents claim that beet pulp can promote intestinal health and regulate blood sugar. However, opponents claim that beet pulp is an inexpensive filler.

The remaining ingredients in this Hill's Science Diet Puppy Large Breed recipe are unlikely to affect the overall rating of the product.

Our analysis of the ingredients show that this product derives a considerable amount of protein from non-meat ingredients. This is an undesirable property because plant based protein often lacks many of the necessary amino acids required by dogs. This property is typically found in lower quality products.

Final Thoughts

In summary, we recognize that this product does not contain any artificial colors, artificial preservatives, or anonymous meat ingredients.
