so after many nights of research because i'm slowly losing my mind with all the constant scratching and chewing.... I'm pretty certain Riley has food allergies but primarily he's allergic to chicken. so far thats the ONLY thing even our vet can see he would be allergic to. Chicken is the common denominator. All of the symptoms he has such as constant scratching, paw chewing and licking, hair loss, dandruff/dry itchy skin he's had since we got him. He's only gotten worse. We know he's allergic to fleas but we're currently flea free. I'm going to switch him to a lamb based kibble when i get the chance. Shasta was itchy as well when she was on purina but the puppy food she's on now is lamb based with no chicken and she's not itchy or anything. Shelby is still on the purina and she's itchy. So i think i have a pack of dogs allergic to chicken. it would certainly explain Riley and all his aggravating issues that get him banned from the room and/or yelled at. guess i'll have to give it a shot and see. Payday will be here on halloween so i'll start there.
