I would appreciate any help with this: I have a 8yr old lab/pit mix. He is about 80lbs., is fed Nutro Natural Choice lamb and rice, and is bathed & groomed regularly. Despite this, he has had an oily and flakey (dandruff-like) coat for some time. After bathing, his fur will be normal for about a day, but then get increasingly oily throughout the week. The skin around his lower back (above his tail) also gets very dry and flakey as well. It seems to be getting worse despite my efforts. I have tried head and shoulders shampoo, but this did not seem to help much. My friend sugessted that it might be his diet, but he is getting a good food. From my experience, Nutro usually seems to help solve most skin problems, not cause them. Does anyone have any suggestions?!
