Thanks guys. Sometimes it's his eyes but normally it's his rims. He's all black so it shows up very dramatically. No pictures have turned out well enough to show it. We've switched him to Blue Buffalo brand food but he still scratches a lot around his face. Not as much as he used to but he still scratches. I'll get him tested as soon as I can get him in.
Could it be something with his third eyelid? My Arnie's dad, Davie, had this and when he had a CERF exam at a BCOA National in St. Louis, it was noted. The vet said that he rarely sees this in Bs. In some breeds this is a problem-can be disqualified in the show ring if it is extremely noticeable. Davie's eyes just looked different and it was because it was non-pigmented. He did not need anything done to correct it. It was not a protrusion or a cherry eye or anything like that. A problem with a third eyelid can sometimes cause dry eye.
