My non-greyhound has experienced allergies over the years. He is now 8 years old. I have understood and have been told it was food allergies. I stopped all chicken and grain products. He was fine on Natural Balance for about 1.5 years and then started having problems. Long story short, he now has swelling in his anal area, His anal glands were expressed, and I agreed to a one time shot of Cytopoint.
He was checked one week after the injection, and he seemed to be improving (less scratching)
Two weeks later, he was checked again by vet and the swelling in his anal area hadn't improved. So, vet diagnosis: food allerigies. They suggested hypoallergenic food (Royal Canin or Hills). I tried the Hills before, and his stools were like pudding, so they allowed me to return it and gave me credit.
My question is, the Hills diet was hydrolyzed chicken protein. The Royal Canin is also hydrolyzed protein (not sure if it is chicken),,,and it's very expensive. I am unsure about purchasing it, since he didn't tolerate the Hills hydrolyzed protein.
I know it's a different brand, but I am not sure what to do here.
