Helps reduce skin and GI reactions that may be a result of sensitivities to common proteins found in pet foods

Helps minimize risk of reaction with proteins that are broken down to a size that’s less likely to be recognized by the immune system

Reinforces the skin barrier with essential nutrients to support healthy skin in dogs with skin sensitivity and irritation

Helps support healthy digestion with an exclusive blend of fibers

Whether a veterinarian has determined through an elimination diet trial that your dog has food sensitivities or that he requires long-term support for his skin and GI issues, your veterinarian recommended Royal Canin Hydrolyzed Protein for a reason. This highly palatable diet is designed for adult dogs. It’s formulated with hydrolyzed proteins, composed of low molecular weight peptides, so they can be absorbed in the digestive tract with a reduced risk of triggering an immune reaction. Optimal amounts of B vitamins and amino acids reinforce your dog’s skin barrier. Omega-3 fatty acids EPA and DHA help promote healthy skin and coat. An exclusive blend of fibers helps support healthy digestion in dogs prone to digestive upsets, including diarrhea. And with strict manufacturing procedures to avoid cross contamination, you can confidently feed Royal Canin Hydrolyzed Protein long-term to dogs with food sensitivities. Ask your vet about feeding your adult dog Royal Canin Veterinary Diet Hydrolyzed Protein Adult HP dry dog food as a complement.

So thankful this is available

I did not even know this existed until my 14 year old dog started to have issues with protein. It has been lifesaving for her. She gobbles it up without hesitation. I mix the canned food with the HP dry food to give her some variety since she cannot have anything else. I also give her the HP treats and she looks forward to getting them every night. The consistency of the canned food is quite different than anything else I had used in the past and it gets quite firm after being refrigerated so have a nice strong fork or knife to use to cut it up. Also be sure to order before you're on the last can because you can't just walk in and buy some like other pet foods.

Best dog food ever

My dog has been eating the Hydrolyzed protein diet for months now. Her rashes have all gone away and she has even lost weight. It may seem more expensive than other dog food, but I have saved so much on vet bills and allergy medication it is well worth the cost.

Has probably saved our dogs life

Our dog has IBD. Everything causes bloody stools and some vomiting except the canned hydrolyzed protein. She does get tired of it, and it's a bit pasty but unfortunately it's the only thing she can eat. She can eat only 1 hydrolyzed cookie and about 12 pieces of the hard food before they cause additional bloody stool. I'm grateful forthis product as we went through many months of trying other food items with bad results.

Black Spots

A couple of people mentioned the black spots. I had my dermatologist check to see if it was mold. It was not. So I took pictures, and wrote to RC. Here is what I was told. Smaller spots: This can occur when the minerals cook and clump slightly, causing some slight discoloration during the baking process. These discolorations can be more visible in the HP since it’s light in color. The Hydrolyzed Protein cans are safe and healthy to feed, these spots will not affect the benefits or nutritional value. Larger spots: Typically attributed to the lecithin in the product that helps to thicken the formula. This ingredient is not very soluble in water so it does not always completely dissolve during the baking process. Due to this, it is possible to sometimes see spots of this substance in the food. Hope this helps.

Black spots?

I’m having the same black spots as another customer that asked 7 months ago but the question was not really addressed. Just wondering as to what these tiny black spots actually are because we see them too but only in 2-3 cans per box of 12

Has not helped for IBD

We’re feeding it to her as instructed by vet for at least a month now, no improvement in her IBD, plus the food causes the most absolutely horrific farts.

My Vet recommended my 10 year old cocker spaniel switch to the Hydro diet due to chronic ear and skin infections. We are 2 weeks into the diet, Lucy LOVES the wet and dry foods, and Hydro treats. Her ears look great and her coat is shiny and itch free. Thank you so much for this Awesome product

The RC Hydrolyed soft food

I just have a question about the soft food. I opened the new can and noticed black spots. Is that normal for this food? I gave it 4 stars because my pet is tolerating the hard food well.
