Odie is a bit allergic too, but he's not on prescription drugs. Last time I went with him to the vet, he had a big hotspot on his back. Dr. gave him a shot of Depo-Medrol for the allergy, and baytril and Pen-G as antibiotics (cause it was infected). His ears were also irritated, and Dr. gave me an ear wash with Dexamethasone in it, which has helped greatly. Since I've been cleaning his ears with it, his ears are normal and he rarely itches. Dr. also reccomended me to change foods to z/d, which is an hipoallergenic prescribed diet. I read around and asked around, and decided to try other hipoallergenic food, since z/d apparently is not too tasty for them. Today, I'm going to buy a bag of pro-plan formula for sensitive skin and stomach, which is made with salmon, and does not contain corn. If that fails, I'm going to see if the vet can order me d/d which is also an hipoallergenic food, and if that also fails, then I'm going with z/d.
