What are Royal Canin Allergies?

Many people have differing opinions on the quality of the Royal Canin products.  What should matter most to you: is it a good choice for your dog? Royal Canin produces good foods for many different stages of a dog’s life as well as different breeds and different medical conditions. However, no matter the quality, if your dog is allergic to an ingredient within the food, it is not the best choice for your dog. Symptoms of allergies can develop either immediately or over years of your dog having consumed the same diet. If your dog is diagnosed with a food allergy, treatment is straight-forward and prognosis for a full recovery is good.


Royal Canin is a brand of dog food known for its variety of diets, including a veterinary line. While this food may be an excellent source of nutrition for some dogs, it is possible your dog may be allergic to it. If you suspect your dog has an allergy to Royal Canin, consult with your veterinarian.

Symptoms of Royal Canin Allergies in Dogs

Symptoms of allergies from Royal Canin in dogs will vary because each dog may be allergic to different ingredients resulting in different symptoms.  Allergy symptoms may include

  • Runny nose
  • Runny eyes
  • Itchy skin
  • Dry, flaky skin
  • Poor skin conditions
  • Poor hair coat
  • Hair loss
  • Bumps/rash 
  • Hives
  • Chronic ear infections
  • Obsessive licking/chewing of feet
  • Inflamed, red paw pads
  • Gastrointestinal upset


Royal Canin produces a wide variety of foods for dogs of all stages in their life.  They have foods with different protein sources, foods with and without grains, wet foods and dry foods.  Depending on which ingredient your dog is allergic to your dog may or may not be allergic to one, some, or all of the Royal Canin products.

Causes of Royal Canin Allergies in Dogs

If your dog has allergies, it is his body’s way of protecting itself from something it thinks will harm it. While the item in question is actually harmless, the body doesn’t recognize it as such. The body finds the allergen dangerous and mounts a protective response to the threat. Your dog’s body produces an immune response to the allergen ingredient. This allergic response may develop quickly or may develop over a period of years of consuming the same diet. Many food-related allergies happen after the dog suffers from an infection involving the stomach or intestines.

Diagnosis of Royal Canin Allergies in Dogs

When you first arrive at the veterinary clinic, the veterinarian will start with a physical exam. This will allow her to take note of all your dog’s symptoms. If your dog has watery eyes, the veterinarian may perform fluorescein staining to check for a scratch on the eye that could possibly cause the watering. If your dog’s skin is irritated, the veterinarian may take a skin scraping to check for external parasites or bacterial overgrowth.  

Blood work will be performed to give the veterinarian a broad look as to how the internal organs are functioning and to rule out other possible causes such as a parasitic infection.  A complete blood count (CBC) and chemistry panel will provide the veterinarian with needed information for proper assessment.  If your veterinarian feels it is necessary, she may also perform a urinalysis for further evaluation of kidney function. 

Bicom testing is another method of determining Royal Canin related allergy in your dog. Bicom testing is also known as bioresonance. This method believes every being and substance in the world emits its own electromagnetic wave. Bicom testing is not commonly seen in veterinary practices because it is considered an ‘alternative’ medicine. Many holistic veterinarians use the Bicom testing with an extremely high success rate, but other veterinarians believe this method does not work. If you look up Bicom testing, some methods are potentially used to ‘retrain’ the body’s electromagnetic waves to relearn the allergen does not actually pose a threat and should therefore stop producing an allergic response. Other veterinary practitioners typically use it to find out if your dog is compatible with the food or not. If it is not good for your dog, then you simply remove that food from his diet and the allergic symptoms should stop. The veterinarian takes a blood sample from your dog and tests different food items and substances to see if it has a ‘good’, ‘neutral’ or ‘bad’ response.  If the response is ‘good’, then the item puts out a wavelength that is compatible with your dog’s blood which means no adverse reactions should occur. If it is ‘neutral’, the item being tested does not put out a wavelength that alters that of your dog. If the response is ‘bad’, the item being tested causes your dog’s blood wavelength to become stressed. Stressed blood leads to a stressed body, and therefore, an allergic reaction. The main downside to the Bicom testing for an entire food, is it does not tell you what specific ingredient your dog is allergic to, just that something in the food reacts poorly with your dog. 

As you can see, when it comes to diagnosis of Royal Canin allergies in dogs there are very few diagnostic tests you can run.  A dietary trial is the most frequently used method. In a dietary trial, you have to feed your dog a novel diet, meaning you feed him a diet without any suspected allergen ingredient whatsoever. It is recommended that you feed your dog the novel diet for at least 90 days before you can get a reliable diagnostic. After the 90 days, if resolution of the allergic symptoms occurs, you then must reintroduce Royal Canin to his diet.  If a relapse in allergy symptoms occurs once the Royal Canin is reintroduced, then you know the source. If symptoms do not return with the reintroduction of the Royal Canin, then it was a source other than the food.

Treatment of Royal Canin Allergies in Dogs

While it may be a long process, if you are able to discover the actual ingredient your dog is allergic to, you may or may not be able to keep him on Royal Canin food. In addition, once you know the actual allergen, you can then have strict control over your dog’s diet and can keep him from ingesting it in any form of food, treat, or supplement.

Though the  veterinarian will prescribe a medication to help with the itching your dog may be suffering from while trying to diagnose the cause, it may cease it’s healing properties in time. If you do not remove the source of the itching, you will have to continue to give the prescription and possibly continuously increase the dose as time goes on. Removing the allergen completely will also help avoid chronic infections.  If the allergen remains in your dog’s food, it will continue to weaken his immune system and may lead to more and more visits to the clinic.

Recovery of Royal Canin Allergies in Dogs

Once you discover the exact allergen causing issues in your dog and remove it from his diet, all of his allergy symptoms should stop. While there have not been any cases of death from an allergy to Royal Canin, the longer your dog is eating a food that weakens his immune system, the higher his chances he may develop a more serious secondary health concern. Once your dog is consuming a diet healthy for him, his immune system will return to full strength and prognosis of a full recovery is good.

Has Symptoms

Rash, bumps, dry flaky skin,
Redness of skin

A few months back, jojo started Urinary SO for a bladder stone. We were told she would have to stay on this food regularly. Now the stone has gone and she has a rash,her belly is red, she has patches of dry flakey skin. She is consistently licking and scratching now.

I have two 7 year old shih tzus. In early August one of them was diagnosed with bladder stones and the vet put her on Urinary SO. She had the stones surgically removed in mid-August, but has remained on the food. We switched our other dog to this food as well for prevention, but now after being on this food for a while, both have become extremely itchy. They are constantly biting, scratching and licking their skin. They have also developed many small bumps on their bodies. I'm pretty sure it's an allergic reaction to the corn and also possibly the large amount of rice in this food. I'm switching my one dog that didn't have the stones off of it immediately. If I see improvement which I'm pretty sure I will, then I will talk to my vet about taking the other dog off too.

My shih tzu, Sophie, 9 years old has exactly the same thing.
I want to change the food to check what is cause that allergy, but the vet told me to keep it forever.
the red belly, rash and dry flaky skin is for over 10 months, I try antibiotic, shots, shampoo and etc.....nothing works.
Should I try to change the food anyway ?

I have a Bichon and Shitzu, and both eat Royal Canin once a day and generally chicken for their other meal. I have been reading about Royal Canin allergies and can say that the Bichon is always liking his feet and having a go at his legs. We have had the Bichon for 5 years - he is a rescue about 9 now. From the reading I have done I feel that I am not doing the Bichon any favours with the Royal Canin. I feel that we should change his diet gradually, to what I dont know. I was thinking about trying to get him on a grain free, sweet potatoe lamb diet. I would appreciate any comments - thankyou. Richard F

Whilst the allergy isn’t to Royal Canin itself, it would be an allergy to an ingredient in the food; dogs may be allergic to beef just as much as grains so going grain free may not be a cure all. I would recommend doing allergy testing to see if any particular allergen comes up since this would save time instead of doing trial and error with different dog foods over the next year or so. You could try feeding a limited ingredient diet and if you notice an improvement you can introduce a different food and look out for paw licking and other symptoms. Regards Dr Callum Turner DVM

There are a few possible causes for the symptoms you are describing which may include food allergies, but may also include infections, parasites, autoimmune disease among others; you should have your Veterinarian check the bumps and possibly try a restricted ingredient diet for a few weeks to see if there is any improvement.

My dog is on Royal Canin wet food and has been since 18th September due to stomach upset. He attended vet hospital and I was told to feed him this for six weeks. I did this but now for past 2days he is scratching and nibbling his paws. Today I am reintroducing him to his original food which was Chappie Original

Biting at the paws is a typical sign of food allergies but we would have expected to see a reaction to the food after Finley started on the Royal Canin food; although dogs may become allergic to an ingredient after a period of time. Changing the food back should be done gradually and you should make sure that Finley’s stomach is able to tolerate the Chappie food, it may be a case of trying a different sensitive diet.
