Well I think the hydrolyzed protien was an error. He has been getting the dry food (which he loves) for exactly one full day and this morning I woke up and he has two massive losses of hair on his neck. He never rips the hair out. He must have some allergy to this food.

This morning at least he is scratching left and right.

It seemed like we were on a good track when we stopped the chicken and gave him rabbit and duck so I think I will do that.
