  • What’s better? Kangaroo? Limited ingredient? Or hydrolyzed protein?

There are quite a few ways to supply proteins to a dog. I think that’s an understatement. But in consideration of food allergy, there are three main considerations. That’s novel proteins, limited ingredients, or hydrolyzed proteins. But what’s best?
What do you think about the limited ingredient foods such as kangaroo food? Or do you think we should stick to the Rachael Ray food for her?
ANSWER:
That is an excellent question
You can feed a food that has brand new proteins the dog has never seen, and of course they will have no allergies to that.
But.
Instead of guessing what proteins would be considered “new“ to the dog, there are also what are called “hydrolyzed protein“ diets in which the proteins are broken down from kangaroo Into the essential amino acid’s, thereby no longer being chicken, beef, or kangaroo. Just raw, antigen free protein building blocks. It seems to me in cases of food allergy that, that is the best result we are getting.
However, food allergy is minor, compared to adverse food reactions, which is usually the body rejecting various insecticides and herbicide’s that are used on the ingredients that go into dog food.
I don’t know what comes up when you keyword search “hydrolyzed protein diets” on Amazon. But that is the most sure fire way to find a diet that will not trigger an immune response.
That being said, I really do like the Rachael Ray Peak, just six, and nutrish lines. Simply avoid her diets that contain lentils and peas.
