"Glycerin (glycerol) is a humectant approved by AAFCO for use in pet foods to retain moisture and improve palatability."
Glycerin is a moisture-retaining agent that is generally safe for dogs. However, its source (vegetable or animal-derived) is unspecified, and it adds no nutritional value—it is purely functional for treat texture.
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.
