This Chestnut English Bridle Leather Snap Bell Matches all Mendota style leather collars and leashes and snaps right onto the dee ring of any dog collar. Some people call this style bell a "bear bell" since they were originally used for snapping on to horse saddle bags, packs, etc. to scare away bears. But we like to use them for dogs. The sleigh bell is very nice for winter use since it prevents snow and ice from getting stuck inside the bell and always has a very clear ring.
