Ingredient Analysis

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 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 fourth 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 doesn’t sound very appetizing, chicken fat is actually a quality ingredient.

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 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 next ingredient 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 have failed to hatch.

In any case, eggs are easy to digest and have an exceptionally high biological value.

After the chicken liver flavor, 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.

The next ingredient is corn gluten meal. Gluten is the rubbery residue remaining once corn has had most of its starchy carbohydrate washed out of it.

Although corn gluten meal contains 60% 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.

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 beet pulp. Beet pulp is 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, this recipe includes 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 its nutrient profiles, we question the use of this item in any canine recipe.

In addition, 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.

Next, we find rice protein concentrate. Rice protein is made by removing the starchy part of the grain and leaving the protein.

Even though it contains over 70% protein, this ingredient would be expected to have a lower biological value than meat.

And less costly plant-based products like rice gluten can significantly boost the total protein reported on the label — a factor that must be considered when judging the actual meat content of this dog food.

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 recipe 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.

Nutrient Analysis

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 an average wet product.

The dashboard displays a dry matter protein reading of 19%, a fat level of 23% and estimated carbohydrates of about 50%.

And a fat-to-protein ratio of about 124%.

Which means this Hill’s product contains…

Below-average protein. Near-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.

Our Rating of Hill’s Prescription Diet L/D Canine Canned Dog Food

Hill’s Prescription Diet L/D Canine is a grain-inclusive moisture-rich dog food using only a limited amount of egg product as its dominant source of animal protein.
