The first ingredient in this dog food is dried potato, a dehydrated item usually made from the by-products of potato processing. In most cases, dried potato can contain about 10% dry matter protein which can have a slight affect on our estimate of the total meat content of this recipe.
The second ingredient is venison meal. Venison meal is considered a meat concentrate and contains nearly 300% more protein than fresh venison.
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 potato protein, the dry residue remaining after removing the starchy part of a potato.
Even though it contains over 80% 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 fifth ingredient is hydrolyzed soy protein. 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.
After the natural flavor, we find vegetable oil, a generic oil of unknown origin. The ratio of omega-6 to omega-3 fats in any oil is nutritionally critical and can vary significantly (depending on the source).
Without knowing more, it’s impossible to judge the quality of an item so vaguely described. However, compared to a named animal fat, a generic vegetable oil cannot be considered a quality ingredient.
The eighth 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.
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, we find no mention of probiotics, friendly bacteria applied to the surface of the kibble after processing to help with digestion.
And lastly, this food contains chelated minerals, minerals that have been chemically attached to protein. This makes them easier to absorb. Chelated minerals are usually found in better 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, it’s important to consult your veterinarian.
With that understanding…
Judging by its ingredients alone, Royal Canin Veterinary Diets Canine Selected Protein appears to be a average dry 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.
As a group, the brand features an average protein content of 22% and a mean fat level of 11%. Together, these figures suggest a carbohydrate content of 59% for the overall product line.
And a fat-to-protein ratio of about 48%.
Below-average protein. Below-average fat. And above-average carbs when compared to a typical dry dog food.
When you consider the protein-boosting effect of the potato products and soy protein, this looks like the profile of a kibble containing only a limited amount of meat.
Royal Canin Veterinary Diets Canine Selected Protein is a plant-based dry dog food using a limited amount of named meats and named meat by-products as its main sources of animal protein.
