Product details

Royal Canin Canine Hypoallergenic DR 21 is a complete food for dogs with ingredient and nutrient intolerances. Its reduced calorie formula is perfect for pets prone to putting on weight.

How it works

An intolerance occurs when your dog‘s digestive system is unable to digest a specific ingredient. Hypoallergenic DR 21 uses a balance of proteins and nutrients to limit your pet’s contact with allergenic ingredients. This complete food is made with soy protein hydrolysate, which is hypoallergenic and easily digestible.

When your dog suffers an allergic reaction, their stomach can become sore, their skin irritated and their immune system impaired. Hypoallergenic DR 21 contains high amounts of biotin, niacin and fatty acids to help support their digestive system and repair their skin. This low calorie formula contains moderate fat and high protein ingredients, making it perfect for dogs who tend to overeat.

Key benefits

  • made with soy protein to replace allergenic ingredients
  • highly digestible formula helps your dog absorb essential nutrients
  • packed full of nutrients and fatty acids to improve the digestive system and repair irritated skin
  • reduced calorie formula with high protein ingredients to encourage a balanced diet in dogs prone to putting on weight.

When to use it

An intolerance to nutrients or ingredients in food can make your pet extremely ill. As a result of their allergy, your dog's coat could become duller, their skin dry and irritated and their stomach sore. Switching your pet's food to a hypoallergenic alternative will see them bounce back to their usual selves.

There are a few symptoms you can look out for if you think your dog has an allergy: a rash on their skin, itching, vomiting and obsessive licking are all common symptoms. If you think that your dog has an allergy you should seek veterinary advice immediately. To help minimise the effects of the allergy your pet’s regular food should be swapped for a hypoallergenic formula as soon as possible.

Because veterinary diets are formulated for the nutritional support of pets with specific clinical conditions, we recommend that you only use them under professional advice. For more information on feeding Royal Canin Canine Hypoallergenic DR 21 to your dog, please consult your veterinary surgeon.

  • Great service
    I have used this company for many years and also recommended the company to others. The value for money is good and the reliable service makes receiving deliveries easy and you don’t have to think about it.

  • Great for my dog
    I get this food as my vet put my dog onto it. He has skin problems and IBD so this is great no problems when he eats this food.

  • Good stuff. Very pleased.
    This food was recommended for my 8 year old Staffy, after several nasty tummy upsets. He's around 19.4 kg and gets through 280-300g per day. There have been no tummy upsets since he started on this food (10 months ago), his coat is in great condition, he looks really healthy and loves the taste. It's not the cheapest and it smells quite strong, but it's well worth the money.

  • We had great results using this food for our puppy
    Our vet put our Springrer puppy on this when his was down to 14kg instead of 18kg for a healthy puppy of his age. After 3 months on this food and excluding any other food he was back to where he should be. We have continued to feed this and he loves it so much that I use it as training treats! We would like to move on from this to a more normal diet but we worry about a return of his problems.
