here is another bark collar. Im not fond of the ones that shock like this one. If I wouldnt test it on myself i really dont want to put it on one of the dogs. This one is for medium to large dogs. This one would be too big for my dogs. I put it together and tested it like the instructions said to and that was pretty much the extent of it.
