I have wondered the same thing. My 2yr. old Yorkie, Buddy always scratches, but just recently has been going crazy scratching all the time. The other one doesn't, so I'm beginning to think maybe it is something in his food too. They are so.......fussy though. I've been thru so many dog food in those 2yrs. with these guys. Any thoughts to a good food they might like?
