"A protein derived from boiling collagen out of animal skin, bone, and connective tissue."
Extracting collagen this way concentrates glycine and proline — amino acids with some documented joint and skin support benefit — into a flavorless binder used to hold chews and soft treats together. Functional rather than a meaningful protein source on its own, but not a concerning ingredient. Score: 6/10.
A minor caveat applies — usually a processing step (e.g. rendering into a meal), a moderate allergen history, or a named-but-fattier source — but nothing on our risk watchlist. -1 pt deducted.
