The one that I ordered isn't the one that is on a collar. It's just a device you can put in a room and set it on automatic or you can control it manually. If it seems like it hurts my dogs ears I'll send it back. But we've atleast got to try it b/c Nala will sit and bark and something nonstop and you can't make her stop and we all know how annoying those yorkie barks are, lol. |
