We got the results of an allergy panel on Drummer, and one of the things he's allergic to: beef, we regularly gave him. We thought he was allergic to chicken, but he isn't. He is also allergic to milk, liver, lamb, and pork... and kangaroo (kangaroo?!).
He continues to have his GI issues, and we've had him on pumpkin, rice and fish as well as his dry food (BilJack for sensitive stomachs). He is also taking tylan, an antibiotic; as well as a probiotic. He seems to be improving.
