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.

The dashboard displays a dry matter protein reading of 21%, a fat level of 11% and estimated carbohydrates of about 60%.

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.

Bottom line?

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.

    hi and thanks for the reply – no, she’s not overweight, her weight is good at 10 lbs. – want to keep it there, but her walks are now much shorter and i have to take her to the vet once a week for injections for the arthritis – so now i’m very cautious of how much to feed her

  • Susan

    Hi I wouldnt bother reducing kibble, 1/2 a table spoon isnt much… unless Lexee is over weight, have you looked at Hills Metabolic & Mobility vegetable & Tuna stew…

  • Pitlove

    No I really don’t think it’s from the food. He will vomit bile early in the morning on some occasions. No other symptoms. This was just the first time he did it so close together.

    We used the HP to do a food trial for Bentley to determine if he had food sensitivities. Definitely didn’t smell great. Guess that’s what attracts them to it. The Kangroo doesn’t smell bad at least haha

  • Susan LaFountaine

    Glad to hear your pup is tolerating the Kangaroo well and hopefully the vomiting is not from the food, cuz it sounds as though it is really good food for him. I was reading more about the hydrolyzed protein and I see that they also carry a moderate calorie formula. The vet said that my Sheltie could certainly eat the same food as my Rottie. But his food is a lot higher in fat and she already has a weight problem. I was thinking about maybe purchasing a small bag of the moderate calorie for her since she is constantly trying to steal his. I don’t know what it is about this food, but they both go nuts when I open the bag! Personally, I think it smells awful!!

  • Pitlove

    So sorry for what you and him had to go through. That sounds like a nightmare. Royal Canin HP is complete and balanced so if you want to feed it long term or permanently you most certainly can. Absolutely nothing wrong with playing it safe!

    Things seem to be fine on the Kangroo. He likes it which I was unsure about. He has thrown up two times a week apart since being on it, always in the early AM so I’ll be asking his vet when I go into the clinic on Tuesday for work if I should be concerned about that.

  • Susan LaFountaine

    Oh yes, this illness has scared me to death!! Believe me, I have no plans to change his food, even if the vet says to try it. I do not want to see him go thru that again! The more I read about it, the more I am learning about so many dogs suffering with this, it is so sad. For now, I am very grateful for the Royal Canin HP formula as it has made such a difference for him, you would never know he was ever sick and I am hopeful that he will tolerate this formula for a very long time. But it is good to know that there are others with the same ingredients.

  • Susan

    Hi oh don’t change his diet if he has just started the HA vet diet & is doing well, he needs to be on the HA vet diet for around 9 months to let everything settle & heal, then when he’s doing real well you could slowly add 1 fresh food to his diet, I give a few small pieces of peeled apple as a treat, I always start a new food as a treat first, given around the same time everyday 11am & then I know if the second poo the next day is very sloppy & continues to be sloppy that new food or kibble isn’t agreeing with him, you’ll work it out but what can happen is if they stay eating the same formula for years & years they can start to react to an ingredient in the diet…..
    IBD is an awful disease, I didn’t realise till I read poor dogs stories & watched Patch suffer, it’s very sad the suffering some poor dogs go thru & it seems as they get older they get worse as the years go by….The Hills Z/d is very similar to the Purina HA same as the Royal Canine Hydrolyzed HP formula….so if something happens you have 2 more Hydrolyze formula’s to fall back on… but the fat is higher.

  • Susan LaFountaine

    Thank you for your reply. Goodness, it sounds as though you have had a lot of experience with this! This is the first time I have ever had a dog with such problems and it has been very frightening! At the moment, the formula my pup is on is hydrolyzed soy protein and he is doing so very well on it, I am a little scared at the thought of trying anything else later on. He will need to be on this one for a few months at least to let his system calm down and heal. Best of luck to you and your pup!

  • Susan LaFountaine

    Thank you! Your baby is adorable! I am so relieved that we found something that works for my pup. His explosions weren’t just diarrhea, he would spray bloody water out the back end like it was coming out of a fire hydrant and this would go on for hours! It was so frightening and he would be so exhausted afterwards. You could hear his gut noises clear across the house! And then the very next day, he would be back to normal, solid poop again until the following week. He is doing so much better now. The vet said that after a few months we could try something like the selected protein diet, but I am really afraid to. I don’t ever want to see him go thru that again. The formula he is on now is hydrolyzed soy protein and he is tolerating it very well. Please let me know later on how your pup is doing with the Kangaroo. I may get brave enough to try it later on.

  • Susan

    Hi, how is your boy doing, have you found a food that is agreeing with him? have you looked at the Hill’s D/D Venison & Potato? Hill’s are getting their Venison from New Zealand, I asked the lady at the vets & later I read it on the side of the Hills D/D Venison & Potato bag, but I do live Australia, so I don’t know if the American Hills D/D Venison is made in America or if it comes from Australia?? maybe contact Hills & ask do they make a wet tin food in the D/D Venison & Potato?? I think there’s a duck….With vet diets the protein % is lower so the dog can handle it better …I’ve just started introducing the Hills D/D Venison & Potato kibble….. Patch has never had any luck with Hills Vet Diets so everyone at the vets office & me have our fingers X

  • sharron

    i have Lexee on RC Mobility Support, her arthritis in her leg has now been classed as chronic. I started this food yesterday. I am giving her a 1/4 cup of the dry with a 1/2 tsp of wet. Do i still need to cut back on the dry even though i am mixing in such a small amt of the wet. the dry food has only 324 cals/cup. Her weight is good, she is now down to 10 lbs.

  • Pitlove

    Hi Susan-

    So happy you found a food that is helping your baby feel better. My boy in my doesn’t have IBD but he does have food sensitivities. We had used Pro Plan Sensitive Skin & Stomach for a year and a half with excellent results, but I had been wanting to try Royal Canin Select Protein with him for a while now. About a week ago I switched him to the Select Protein Kangroo and Oats and he’s doing very well.

    I wish your baby continued success. Rotties are wonderful. My boyfriends parents have one that we are dog sitting right now.

    Hi, I also have a dog a Staffy that has IBD, we have not had any real success with vet diets, the Eukanuba Intestinal firmed Patches poos up but caused itchy skin problem, he cant eat chicken & he can’t eat Beet Pulp causes bad acid reflux & breeds his Helicobacter, most vet diets for Intestinal problems have Beet Pulp except the sensitive stomach formula’s, the Royal Canine HP was one of the first vet diets Patch was put on for his skin problems & pooing blood, I didn’t know back then when I first rescued him he had IBD vet said he’s got Colitis foods sensitivities…. In Australia our R/C Vet Diets come from France not America, American R/C formula’s don’t pass our strict pet food laws, anyway our R/C HP dry has 19% fat & caused Pancreatitis, I think the American R/C HP fat is lower, I wish we could get the American R/C vet diets they have the PV, PR, PD & PW formula’s, I tried the R/C wet tin HP food about 2 months ago cause Patch had another flare & vet said she has a few dogs that do better on wet tin food as the kibble is harder to digest, Patch has stomach pain with his IBD & bad acid reflux & Helicobacter but Patches poos were sloppy on the R/C HP wet tin…… He does the best on “Taste Of The Wild” Sierra Mountain, Roasted Lamb dry, maybe it’s cause TOTW use purified water & the probiotics & it just has the Lamb as the only protein & has limited ingredients, back in March I email TOTW when I wanted to try TOTW Southwest Canyon wild boar dry formula cause Patch does well on pork, the TOTW vet nutritionist emailed me back & he said it’s best to stay with a single protein, limited ingredient formula when they have a dog with IBD, the Southwest Canyon formula has 4 different proteins & this may irritate the stomach & bowel…… I hate just feeding 1 food, say something happens & I cant get his food, also I know Patch would get sick of eating the same food 24/7 + I like rotating so if something was wrong with 1 brand formula when you rotate between a few different brands he’s not eating the same food to have any health problems, so I tried the “Canidae” Pure Wild Boar, Canidae Pure is limited ingredient with single proteins in some formula’s & he does OK on Canidae but the protein is 28% & I think it causes pain either the pancreas or stomach we did blood test the other week & everything came back all OK, we have just gotten the Hills D/D Venison & Potato vet diet in Australia so I bought a bag, Patch loves it, cause it’s a new food I’m slowly introducing it with his TOTW vet said take it easy, I have found since I rotate between a few different formula’s it has made his stomach & bowel stronger over the years, I want a vet diet that I can fall back onto just incase later in life Patch might not be able to eat the TOTW & Canidae formula’s or it stops being made or they change ingredients this way I have a vet diet he can eat, the only thing I’m worried about the Hills D/D Venison the fat % is 16.4% TOTW is 15% fat, I just hope he doesn’t get his Acid reflux his skin & coat is looking real good since eating the Canidae Pure Wild….I wish we could get the R/C PR Potato & Rabbit, I suppose I have the TOTW & Canidae so far, just hope he does well on the Hills D/D Venison & Potatoes as well the more foods he can eat the better…
