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 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.
The third ingredient is corn. Corn 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 corn a preferred component in any dog food.
The fourth 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.
The fifth ingredient is barley. Barley 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 sixth ingredient is pork liver. This is an organ meat sourced from a named animal and thus considered a beneficial component.
The seventh ingredient is 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.
After the chicken liver flavor, we find 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.
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 one notable exception…
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.

W/D Canine Canned Dog Food
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, it’s important to consult your veterinarian.
With that understanding…
Judging by its ingredients alone, Hill’s Prescription Diet W/D Canine appears to be an 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 71%.
Below-average protein. Below-average fat. And above-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 product containing a limited amount of meat.
Hill’s Prescription Diet W/D Canine is a plant-based canned dog food using a limited amount of egg product as its main source of animal protein.

A Final Word
The descriptions and analyses expressed in this and every article on this website represent the views and opinions of the author.
The Dog Food Advisor does not test dog food products.
We rely almost entirely on the integrity of the information posted by each company on its website. As such, the accuracy of every review is directly dependent upon the quality of the test results from any specific batch of food a company chooses to publish.
Although it's our goal to ensure all the information on this website is correct, we cannot guarantee its completeness or its accuracy; nor can we commit to ensuring all the material is kept up-to-date on a daily basis.
Each review is offered in good faith and has been designed to help you make a more informed decision when buying dog food.
However, due to the biological uniqueness of every animal, none of our ratings are intended to suggest feeding a particular product will result in a specific dietary response or health benefit for your pet.
For a better understanding of how we analyze each product, please read our article, "The Problem with Dog Food Reviews".
Remember, no dog food can possibly be appropriate for every life stage, lifestyle or health condition. So, choose wisely. And when in doubt, consult a qualified veterinary professional for help.
In closing, we do not accept money, gifts or samples from pet food companies in exchange for special consideration in the preparation of our reviews or ratings.
However, we do receive a fee from Chewy.com for each purchase made as a direct result of a referral from our website. This fee is a fixed dollar amount and has nothing to do with the size of an order or the brand selected for purchase.
