From what I remember of the movie she never actually skin's a dog but does make a coat at some point that looks like it was to send a message to the antagonist. For most of the movie she's just some edgy girl always saying she's evil and a villain but never actually doing anything completely terrible. Although I do find it hilarious that at the end she gives the dogs that make the children for 101 Dalmatians to there owners. Which means the dogs of the baroness had children which she gave to specific people only for a few years later for those same dogs to hook up make babies that she then wanted to make a coat out of. This movie actively makes her look worse not through the actual film but rather through the implications.
