Marshmallow Fluff is not a routine dog treat. Regular marshmallow fluff is a high-sugar treat rather than a toxin, but sugar-free products require an immediate xylitol check and chocolate spreads are different products. A small taste and a package, plate, or batch are different incidents, so identify the exact product before deciding what to do.
