Review of Purina Puppy Chow Large Breed
With Real Chicken
This product is manufactured by Nestlé Purina Petcare.
According to our data, this Purina Puppy Chow recipe provides complete & balanced nutrition for adult dogs and growing puppies. In other words, this formula is AAFCO approved.
Purina Puppy Chow Large Breed With Real Chicken is formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for adult dogs and growing puppies.
We'll begin this review of Purina Puppy Chow Large Breed With Real Chicken with a detailed discussion of the ingredients.
The first ingredient is whole grain corn. Whole grain corn is the entire corn kernel (the germ, bran, and endosperm). Corn is a cereal grain which provides a modest amount of vitamins, minerals, and plant based protein. It also happens to be one of the most controversial ingredients in dog food.
Proponents of corn claim that corn is highly digestible and an excellent source of protein, energy, vitamins, minerals, and essential fatty acids.
Opponents however believe that positive claims in regards to corn are either half-truths or completely false, we'll discuss a few of the opposing arguments.
In regards to digestibility, the claims of "highly digestible" are only true if corn is processed into a meal or flour and subsequently cooked. In regards to the protein contribution, we must note that corn is a plant based protein which does not contain all of the necessary amino acids required by dogs to sustain life. Therefore substituting corn for meat is an unsuitable substitution and actually degrades the overall protein quality of the product.
Finally, we'll discuss the claims about vitamins and minerals in corn. Although corn does provide many vitamins and minerals, it not necessarily an exceptional ingredient in this regards. There are many other ingredients which are more complete and biologically appropriate. Therefore the usage of corn as the primary ingredient in dog food should certainly warrant further questioning.
The second ingredient is chicken by-product meal. Chicken by-product meal is produced by cooking chicken by-products using a process called rendering. By-products are defined by AAFCO as the "non-rendered, clean parts, other than meat, derived from slaughtered mammals." Thus, chicken by-products contain nearly all parts of chickens which are typically not consumed by humans. These parts include the liver, lung, spleen, kidney, stomach, blood, intestine, bone, etc.
Like other meat by-products, chicken by-products are considered controversial, mainly because they are inexpensive ingredients which consumers have equated with slaughterhouse waste. However, manufactures and many experts claim that animal by-products are unjustly criticized. Proponents state that "named" by-products, such as chicken by-products, supply many important nutrients required by dogs.
The third 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.
The fourth ingredient is ground rice. Ground rice is a gluten-free carbohydrate source. As long as the bran and germ of the grain are intact, rice can provide a notable amount of fiber and nutrition. However, because the type of rice ("brown" or "white") is not specified, we cannot make this determination.
The fifth ingredient is soybean meal. Soybean meal contains more than 50% protein. Therefore, soybean can significantly boost the protein content of the product. The inclusion of non-meat protein typically degrades the overall quality of protein in the recipe. This degradation is due to the inferior amino acid profile of plant based proteins.
Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Purina Puppy Chow Large Breed With Real Chicken 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 Purina Puppy Chow recipe.
Next we have beef fat (preserved with mixed tocopherols). Fat is an important part of your dogs diet, beef fat in particular is a good source of essential fatty acids.
The remaining ingredients in this Purina Puppy Chow 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.
In summary, we recognize that this product contains artificial colors. Although the FDA has approved these ingredients in pet food. They are unnecessary and unhealthy additions. Long term exposure can have serious consequences. See our article on artificial food dyes for more information.
The official PawDiet rating for Purina Puppy Chow Large Breed With Real Chicken is 1.0 out of 5.
