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 hydrolyzed chicken liver, an organ meat that’s been chemically broken-down into its component amino acids. Hydrolyzed proteins are considered hypoallergenic.
The third 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 fourth 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.
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 dicalcium phosphate, likely used here as a dietary calcium supplement.
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.
Hill’s Prescription Diet Z/D 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, you must consult your veterinarian.
With that understanding…
Judging by its ingredients alone, Hill’s Prescription Diet Z/D Canine looks like 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 canned 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 Z/D Canine is a plant-based canned dog food using a limited amount of hydrolyzed chicken liver as its main source of animal protein.
However, due to its intentional therapeutic design, this dog food is not rated.
