Dick Van Patten's Natural Balance. Royal Canin makes one too, but it's prescription and the dogs don't like it as much anyway. The Natural Balance is at Petco and some feed stores and independant pet stores.
I use the DVP Duck & Potato and Bear had hardly any tears. But then I had half a bag left of Wellness so I mixed it in. The tears have been horrible. I can't wait til the mix is gone so I can go back to DVP Duck & Potato plain. I notice in the cold outside he starts tearing even more.
