The first ingredient in this dog food 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 second ingredient is hydrolyzed soy protein isolate. Soy protein isolate is a highly refined form of soybean protein with a protein content of about 90%.
In this case, the soy protein has been hydrolyzed which means it has been broken down into its individual amino acid components.
Hydrolyzed protein is valued by veterinary professionals because of its proven and effective hypoallergenic properties.
The third ingredient is coconut oil, a natural oil rich in medium-chain fatty acids.
Medium-chain triglycerides have been shown to improve cognitive function in older dogs.1
Because of its proven safety2 as well as its potential to help in the treatment of canine cognitive dysfunction syndrome (CDS) and chronic skin disorders, MCT can be considered a positive addition to this recipe.
The fourth ingredient is canola oil. Unfortunately, canola can be a controversial item. That’s because it can sometimes (but not always) be derived from genetically modified rapeseed.
Yet others cite the fact that canola oil can be a significant source of essential omega-3 fatty acids.
In any case, plant-based oils like canola are less biologically available to a dog than fish oil as a source of quality omega-3 fats.
What’s worse, this hydrogenated canola oil has also been preserved with TBHQ, a suspected cancer-causing agent.
The fifth 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 sixth ingredient is tricalcium phosphate, a beneficial source of calcium and phosphorus. In addition, this additive is used in canned foods as an emulsifier — an agent designed to disperse a food’s fats more evenly in water.
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 Pro Plan product.
With 6 notable exceptions…
First, we find corn oil. Corn oil has one of the highest (and most unfavorable) omega-6 to omega-3 fatty acid ratios of any vegetable oil. Compared to almost any named animal fat, corn oil cannot be considered a quality ingredient.
So, one must weigh the potential benefits of feeding garlic against its proven tendency to cause subclinical damage to the red blood cells of the animal.
In addition, we find no mention of probiotics, friendly bacteria applied to the surface of the kibble after processing to help with digestion.
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.
We also 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.
Since taurine deficiency appears to be more common in pets consuming grain-free diets, we view its presence in this recipe as a positive addition.
And lastly, this recipe 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 your veterinarian.
With that understanding…
Based on its ingredients alone, Purina Pro Plan Veterinary Diets HA looks like a below-average dry kibble.
As a group, the brand features an average protein content of 21% and a mean fat level of 10%. Together, these figures suggest a carbohydrate content of 61% for the overall product line.
And a fat-to-protein ratio of about 47%.
Which means this Pro Plan product line contains…
Below-average protein. Below-average fat. And above-average carbs when compared to a typical dry dog food.
Because of its hypoallergenic design, this particular recipe contains no meat or any other source of animal protein. So, all essential amino acids appear to be provided by the hydrolyzed protein ingredient.
