A few of my coats and jackets have (had) little beads on the strings that run through a place at the bottom of the coat to pull it tighter (like a drawstring on a pair of shorts or sweats). Taggert has chewed the beads or plastic thingies off of at least 3 of them. He also chewed up the zipper on one of the jackets when it was hanging on the back of a chair in the dining room. That was one of my favorite jackets and it is a reversible one so the zipper is not one that would be easy to replace. Darn little dog!!!
