Marshmallows is not a routine dog treat. Regular marshmallows are mainly sugar and can cause stomach upset, but sugar-free marshmallows may contain xylitol. Packaging and skewers from roasting are the key checks. A small taste and a package, plate, or batch are different incidents, so identify the exact product before deciding what to do.
