The first ingredient in this dog food is beef by-products, an item made from slaughterhouse waste. This is what’s left of a slaughtered cow after all the striated muscle cuts have been removed.
With the exception of hair, horns, teeth and hooves, this item can include almost any other part of the animal.1
Although this item does contain all the amino acids a dog needs, we do not consider beef by-products a quality ingredient.
The second ingredient is water, which adds nothing but moisture to this food. Water is a routine finding in most canned dog foods.
The third ingredient is pork liver. This is an organ meat sourced from a named animal and thus considered a beneficial component.
The fourth ingredient is 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.
The fifth 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 sixth ingredient is chicken. Chicken is considered “the clean combination of flesh and skin… derived from the parts or whole carcasses of chicken”.1
Chicken is naturally rich in the ten essential amino acids required by a dog to sustain life.
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 ninth ingredient is 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.
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 product.
With two notable exceptions…
First, iron oxide is a synthetic color additive used in industry to impart a reddish color to food — and paint. In its natural form, this chemical compound is more commonly known as “iron rust”.
We’re always disappointed to find any artificial coloring in a pet food. That’s because coloring is used to make the product more appealing to humans — not your dog. After all, do you really think your dog cares what color his food is?
And lastly, the minerals listed here do not appear to be chelated. And that can make them more difficult to absorb. Non-chelated minerals are usually associated with lower quality dog foods.

The Bottom Line
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, you must consult your veterinarian.
With that understanding…
Judging by its ingredients alone, Hill’s Prescription Diet N/D Canine looks like a below-average wet product.
But ingredient quality by itself cannot tell the whole story. We still prefer to estimate the product’s meat content before concluding our report.
And a fat-to-protein ratio of about 89%.
Near-average protein. Above-average fat. And below-average carbs when compared to a typical wet dog food.
Free of any plant-based protein boosters, this looks like the profile of a wet containing a moderate amount of meat.
Hill’s Prescription Diet N/D Canine is a meat-based wet product using a moderate amount of beef by-products as its main source of animal protein.
However, due to its intentional therapeutic design, this dog food is not rated.
