I know we've had a thread about this before but I can't seem to find it. I just want to get the ingredients for the ear cleanser. Boomer doesn't have mites, but he's itching his ears like crazy. I did a visual and all I see is dried blood from him scratching. I think he just has some crud build up further down and I need the ear cleanser stuff. Is it more economical to make the stuff myself or just go to the vet and pick it up?
