I think perhaps you are a bit lost. Have you tried contacting a real veternarian nutritionist? They tend to have a better opinion on foods that are healthier and will help stabilize your dog. Even if it’s a balanced raw diet that you are seeking. I don’t believe in all the low quality prescription diets either and I CERTAINLY do not believe that when a dog is sick nutrition isn’t optimal. Of course it is. How would a sick dog on a garbage diet ever get better? If he is starting to do ok on the ultimo try and keep him on it for just a second. Contact a vet nutritionalist and see what they recommend as far as a prescribed balanced raw diet for him. It’s gonna be a long road figuring out what he’s sensitive to and maybe raw just isn’t for him but maybe you can at least switch him back to blue with is better than science diet and the Royal Canin in my opinion.
