Too expensive for me, but my (ex)roomate had her German shepherd dog on this. The vet couldn't figure out what was wrong with her skin, she had raised bumps everywhere. Anne tried dozens of kibbles, including allergy formulas. None of them helped. She switched to raw, and it went away. The NV freeze-dried diet was the cheapest prepared stuff at the time so she encorporated that into the diet. Her dog thrived on it, amazing change.
