I think the issue is about disclosure. Plus, I do think that the protein source does matter for some dogs even if it is hydrolyzed. For example, dogs with PVH (formerly known as MVD) do much better on an amino acid profile that reduces the amount of ammonia byproducts rather than consume some amino acids from meats (i.e, chicken turkey or fish create less byproducts than lamb or beef and this reduces taxing the capacity of an already compromised liver.)
