Great for allergies!

My dog is an "allergy" dog and Hydrolyzed Protein dog food has been a blessing! I had to try something because he was constantly itchy and scratching and kept getting skin infections and hot spots every month. After switching his food to HP he improved by 90% and has been on it for years now.

Has kept most of the allergies at bay.

She's doing much better with the skin issues. She's a picky eater, but seems to accept this quite well.

It helped my puppies digestion

We were struggling to get weight on out puppy as she burns the calories quickly but had a very sensitive digestive system. This has been the trick!

Smelly but yummy

Our dog was on the Hydrolized Protein Dry food for years and other food was strictly forbidden due to allergies. When we decided to try the canned food she seemed to like it and we feel better feeding her a different textured food. She loves it (apparently!!) because she gobbles it down.

Dogs love it

I have three dogs, my middle one has food allergies so my vet recommended the Hydrolyzed Protein... they all love it, must have good flavor since they all get excited at meal time.

It saved my dog.

I have been using the hydrolyzed protein food for about 3 months. My dog had a intestinal episode and was really sick, and we thought it was just a passing thing. However, a month later it happened again and I almost lost him. That is when the vet mentioned pancreatic issues in older dogs and introduced me to Royal Canin. We have had no attacks since and his fur is just beautiful and so soft now. I am very pleased with this food.

Consistent texture and content

This us the only dog food that my Sophie eats. We don't give her people food so for a good girl treat we give her the dry version of this food. My only wish is that it came in smaller cans for smaller dogs. That way I can give her a fresh dish of food. When it's refrigerated it's it has to be warmed. Can't say anything bad except the price is crazy!! Thankful that I don't have a large dog or I'd go broke. Can't even imagine.

Very Palatable HypoAllergenic Option!

We've had our Brussels on Hill's z/d for nearly five years and while it's aided with his food allergies, it hasn't fully abated his symptoms. After our veterinarian's recommendation, we decided to try Royal Canin's Hydrolyzed Protein and we've had great results! We've been able to wean him from chronic medications to assist with stomach upset and skin flare ups, and he LOVES the canned diet. Would recommend any day!

I have a 12 year old Boykin spaniel with IBD. She was operated on last year to determine this diagnosis. Since then she has been on a very strict and limited diet. This canned food she loves and I never have a problem with her not eating. It has literally saved her life
