The first ingredient in this dog food is water, which adds nothing but moisture to this food. Water is a routine finding in most canned dog foods.
The second ingredient is rice. Is this whole grain rice, brown rice or white rice? Since the word “rice” doesn’t tell us much, it’s impossible to judge the quality of this item.
The third item is chicken fat. This ingredient 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 doesn’t sound very appetizing, chicken fat is actually a quality ingredient.
The fourth 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 ingredient is soybean oil, which 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-3’s, it’s considered less nutritious than flaxseed oil or a named animal fat.
The sixth ingredient is egg product, an unspecified (wet or dry?) form of shell-free eggs. Quality can vary significantly. Lower grade egg product can even come from commercial hatcheries — from eggs that failed to hatch.
In any case, eggs are easy to digest and have an exceptionally high biological value.
The next ingredient corn starch, a starchy powder extracted from the endosperm found at the heart of a kernel of corn. Corn starch is most likely used here to thicken the broth into a gravy.
Corn starch isn’t a true red flag item. Yet we’ve highlighted here for those wishing to avoid corn-based ingredients.
The eighth ingredient is corn gluten meal. Gluten is the rubbery residue remaining once corn has had most of its starchy carbohydrate washed out of it.
This ingredient can notably boost the total protein reported on the label — a factor that will 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 Hill’s product.
With 6 notable exceptions…
First, we find powdered cellulose, a non-digestible plant fiber usually made from the by-products of vegetable processing. Except for the usual benefits of fiber, powdered cellulose provides no nutritional value to a dog.
Next, this recipe includes fish oil. Fish oil is naturally rich in the prized EPA and DHA type of omega-3 fatty acids. These two high quality fats boast the highest bio-availability to dogs and humans.
Depending on its level of freshness and purity, fish oil should be considered a commendable addition.
In addition, we find beet pulp, a controversial ingredient, a high fiber by-product of sugar beet processing.
Some denounce beet pulp as an inexpensive filler while others cite its outstanding intestinal health and blood sugar benefits.
We only call your attention here to the controversy and believe the inclusion of beet pulp in reasonable amounts in most dog foods is entirely acceptable.
Next, 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.
Additionally, 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.
And lastly, this product contains menadione, a controversial form of vitamin K linked to liver toxicity, allergies and the abnormal break-down of red blood cells.
Since vitamin K isn’t required by AAFCO in either of its dog food nutrient profiles, we question the use of this substance in any canine formulation.
Although this is a prescription product, our review has nothing to do with the accuracy of claims made by the manufacturer as to the product’s ability to treat or cure a specific health condition.
So, to find out whether or not this dog food is appropriate for your particular pet, it’s important to consult with your veterinarian.
With that understanding…
Based on its ingredients alone, Hill’s Prescription Diet L/D Canine appears to be a below-average wet product.
And a fat-to-protein ratio of about 134%.
Which means this Hill’s product contains…
Below-average protein. Above-average fat. And above-average carbs when compared to a typical canned dog food.
When you consider the protein-boosting effect of the soybean and corn gluten meals, this looks like the profile of a wet food containing a limited amount of meat.
