I am training my dog to be a hearing dog. She's a medium lab size (border collie/lab), and we haven't done the 'out in public' part yet. She's a super mellow, easy, friendly dog, so I don't anticipate any problems as far as behavior, and really, the skills are a lot of work already... but i was wondering if any of y'all had old dog vests or in training patches or anything like that, that you aren't using anymore... i'm looking to get some stuff, so when she's ready, we can go out. Thanks!
