Boddy D- I wanted to explain MY vet’s reasoning for wanting my dog to use the Royal Canin prescription diet for his food trial since El Doctor urged you to stay away from it based only on the ingredients.

When a protein is hydrolyzed, they break it down into its component amino acids which in turn makes it harder for the dog to have a reaction to. Now of course if your dog had a soy allergy, he would still react. Other reason for my vet wanting me to use the prescription diet and not an over the counter limited ingredient diet is because, when Royal Canin has their prescription allergy diets manufactured the machine is sterilized after each “run”. It can not be guarenteed that commercial dog foods labeled as “limited ingredient” use those same quality control measures. In fact, I believe it was another poster on here, Aimee, that once said that some over the counter limited ingredient diets had tested positive for proteins that should NOT have been in the food. Cross-contamination is NOT what you want when conducting a food trial.

The reasons my vet and I spoke about that I listed above is why when doing a TRUE food trial to test for food allergies, the prescription diet (while it may be expensive) is the recommended food. However, you’re welcome to think on what both myself and El Doctor have suggested and make your own decision.
