Who makes the badest shock collar for dog training? I have a 2yr bldhound that is turning everything into the DMZ! I have a invisible fence on him (shaved his neck) it's the meanest one that they make turned up as high as it will go and he doesn't care one bit. It's getting to the point to where I think it will be me or the dog that has to go. I need some help b/c I do not want to have to buy 2 of them. Thanks guys in advance!!
