For my German Shepherd from the performance breed, this feed has emerged as an ideal. Super friendly, no bloating, great coat and it provides him with everything he needs. But it is a food for working dogs! Since you realize if the dog has eaten the stuff over a then he has power that he wants to get rid of. I would recommend Hundesport before he misses his zest for action on the furniture. Mine has a part of the sofa, a piece of staircase (tiled!) And a portion of "bitten or gescharrt" from a wall. Long live the dog sport!
