I have read all the posts about allergies. But my dog has been tested and he is allergic to dust,mold,corn pollen,several weeds and tree pollen. We have tried for 4 years several different approches to treat him. The only thing that works is steriods. He does not have food allergies. We tried him on several organic foods with no sucess treating his skin allergies. Does anyone have a miracle out there? I would really love to get him off the steriods. The one good thing is that all of his liver functions are normal right now. But it will catch up with him some day.
