We have been feeding the Bison to our two dogs for well over a year and they loved it. I bought a new bag of the tightly packed bison and overnight, they just stopped eating. I thought maybe they just got tired of the food, so I bought a small Ocean Blue bag that had been on the shelves awhile and they loved it. So, I bought a 33 lb. bag that was in the new tightly packed bag. From the first cupful, they have refused to eat it. There is definitely something going on with the newly packaged Bison and OceanBlue. At this point, I think I will need to switch brands, but has anyone had any problems with any of the other Timberwolf blends?
