Animal feeding tests using AAFCO procedures substantiate that Hill's Science Diet Puppy Chicken and Barley Entree provides complete and balanced nutrition for growing puppies and pregnant/nursing dogs.
We'll begin this review of Hill's Science Diet Puppy Chicken and Barley Entree with a detailed discussion of the ingredients.
The first ingredient is water, which increases the food's moisture content.
The second ingredient is chicken. Chicken is the most common meat ingredient used in dog food. It provides high-quality protein and fat. However, more than 60% of chicken is water.
The third 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 fourth ingredient is cracked pearled barley. Cracked pearled barley is barley with the outer husk and bran layers removed. Similar to regular barley, cracked pearled barley provides carbohydrates and dietary fiber. Cracked pearled barley is however not as nutritious as regular whole grain barley.
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 Hill's Science Diet Puppy Chicken and Barley Entree 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 pork liver. Pork liver is an excellent organ meat which provides high quality protein and fat. In addition, pork liver provides many essential vitamins and minerals.
The 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.
Then we have dicalcium phosphate. Dicalcium phosphate (misnomer for dibasic calcium phosphate) is commonly used in pet food and treats as a dietary calcium supplement. It can also be found in breakfast cereals, enriched flour, noodle products, pharmaceutical tablets, and toothpastes.
Moving on, we have iodized salt. Iodized salt is simply table salt mixed with very small amounts of iodine-containing salt. Iodine is an important natural element required by dogs to maintain good health.
Moving on with this review, we have calcium carbonate. Calcium carbonate is a naturally occurring mineral supplement. Although it's often used as a dietary calcium supplement, it can also be used as a preservative or color retainer.
The next ingredient in this review is potassium chloride, which is a potassium supplement.
Our next ingredient is vitamin E supplement. Vitamin E is an essential vitamin required by dogs.
The remaining ingredients in this Hill's Science Diet Puppy recipe are unlikely to affect the overall rating of the product.
Our analysis of the ingredients show that this product derives a substantial 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 does not contain any artificial colors, artificial preservatives, or anonymous meat ingredients.
The official PawDiet rating for Hill's Science Diet Puppy Chicken and Barley Entree is 3.0 out of 5.
