Which Hills Science Diet Adult Dry Recipes Get Our Best Ratings?
Hills Science Diet Adult Dog Food receives the Advisors mid-tier rating of 3.5 stars.
The Hills Science Diet Adult product line includes the 26 dry dog foods listed below.
Each recipe includes its AAFCO nutrient profile: Growth (puppy), Maintenance (adult), All Life Stages, Supplemental or Unspecified.
Recipe and Label Analysis
Hills Science Diet Adult Small Paws Chicken Meal and Rice was selected to represent the other products in the line for detailed recipe and nutrient analysis.
Ingredients Analysis
The first ingredient in this dog food is chicken meal. Chicken meal is considered a meat concentrate and contains nearly 300% more protein than fresh chicken.
The second ingredient is brewers rice. Brewers rice is a cereal grain by-product consisting of the small fragments left over after milling whole rice. Aside from the caloric energy it contains, this item is of only modest nutritional value to a dog.
The third ingredient is wheat. Like corn, wheat is an inexpensive and controversial cereal grain. And aside from its energy content, this grain is of only modest nutritional value to a dog.
For this reason, we do not consider wheat a preferred component in any dog food.
The next ingredient is soybean meal, a by-product of soybean oil production more commonly found in farm animal feeds.
Although soybean meal contains 48% protein, this ingredient would be expected to have a lower biological value than meat.
And less costly plant-based products like this can notably boost the total protein reported on the label a factor that must be considered when judging the actual meat content of this dog food.
The fifth item is sorghum. Sorghum (milo) is a starchy cereal grain with a nutrient profile similar to corn.
Since it is gluten-free and boasts a smoother blood sugar behavior than other grains, sorghum may be considered an acceptable non-meat ingredient.
The sixth ingredient is chicken fat. This item is obtained from rendering chicken, a process similar to making soup in which the fat itself is skimmed from the surface of the liquid.
Chicken fat is high in linoleic acid, an omega-6 fatty acid essential for life. Although it doesnt sound very appetizing, chicken fat is actually a quality ingredient.
The seventh ingredient is barley, which is a starchy carbohydrate supplying fiber and other healthy nutrients. However, aside from its energy content, this cereal grain is of only modest nutritional value to a dog.
The next item is corn. Corn is another cereal grain and subject to the same issues as wheat (previously discussed).
After the chicken and pork liver flavors, we find flaxseed, one of the best plant sources of healthy omega-3 fatty acids. Provided theyve first been ground into a meal, flax seeds are also rich in soluble fiber.
However, flaxseed contains about 19% protein, a factor that must be considered when judging the actual meat content of this dog food.
From here, the list goes on to include a number of other items.
But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of this Science Diet product.
With 6 notable exceptions
First, soybean oil is red flagged here only due to its rumored (yet unlikely) link to canine food allergies.
However, since soybean oil is high in omega-6 fatty acids and contains no omega-3s, its considered less nutritious than flaxseed oil or a named animal fat.
Next, we find peas. Peas are a quality source of carbohydrates. And like all legumes, theyre rich in natural fiber.
However, peas contain about 25% protein, a factor that must be considered when judging the meat content of this dog food.
In addition, we note the use of taurine, an important amino acid associated with the healthy function of heart muscle. Although taurine is not typically considered essential in canines, some dogs have been shown to be deficient in this critical nutrient.
This recipe also contains sodium selenite, a controversial form of the mineral selenium. Sodium selenite appears to be nutritionally inferior to the more natural source of selenium found in selenium yeast.
We also find no mention of probiotics, friendly bacteria applied to the surface of the kibble after processing to help with digestion.
And lastly, the minerals listed here do not appear to be chelated. And that can make them more difficult to absorb. Chelated minerals are usually associated with higher quality dog foods.
Nutrient Analysis
Based on its ingredients alone, Hills Science Diet Adult looks like an average dry kibble.
The dashboard displays a dry matter protein reading of 25%, a fat level of 16% and estimated carbohydrates of about 51%.
As a group, the brand features an average protein content of 24% and a mean fat level of 15%. Together, these figures suggest a carbohydrate content of 53% for the overall product line.
And a fat-to-protein ratio of about 60%.
Which means this Science Diet product line contains
Below-average protein. Near-average fat. And above-average carbs when compared to other dry dog foods.
When you consider the protein-boosting effect of the soybean meal, flaxseed and peas in this recipe, and the corn gluten meal contained in other recipes, this looks like the profile of a kibble containing just a moderate amount of meat.

Heres an actual user review
Sample buyer review Ive tried 2 other brands for our German Shepherd and after 10 months her bathroom business continued to be a mess. So since she was almost a year old I switched her to the Hills Diet. After a couple weeks her poop was noticeably more solid so that we could easily pick it up on walks and in the yard. I think thats a great barometer to see if her body works well with this food and it does!
