when he comes up to you make him sit, give the cheese and put on the lead. once that works stop giving the cheese.
LOL
A good way to introduce these things, and to reinforce them, and to create positive associations.
Also a good way to get a "hard" dog run over by a truck. IMO you're teaching him that coming when he's called is a neat trick.
He'll do it as long as there's nothing more interesting to him than cheese, or a pet on the head. When there is, he'll blow you off.
Most VHD's are "hard" dogs. Not all are, but I've been to enough trainings to see a lot of dogs in action and most are not exactly born to be obedient little wallflowers. They're bred to be independent, curious, energetic, and assertive. They'd be useless as bird dogs if they weren't.
Dogs also have interests of their own, and a hierarchy of those interests. A dog who loves running in the field, who knows he'll get treats at home, but only gets to go in the field and romp for an hour or so, won't give 2 ****s about treats in the field. I know some people believe dogs are dumb, but they seem smart enough to think, "I can get cheese later, but
right now running across the highway after that rabbit is more FUN!!!" Between having a dog maimed or killed, and giving the dog a zap on the collar, I choose the zap.
Some dogs are natural "pleasers". Others do need
some negative consequences. So far, I haven't seen pinch collars, slip leads, etc. that are 200 yards long. Let me know if you do.
That said, I wouldn't use an e-collar without professional, hands-on assistance first. We worked with a one-on-one trainer who started with us, first, and the dogs after that. If in doubt about a particular situation, we'll err on the side of caution, and don't and won't use it in that situation. This is equally true of ANY training tools and techniques. Ditto for using anything in anger. It's wrong, and it will mess up your dog and you. Our dogs live inside with us, share the couch with us, climb in bed with us, lick off our used dinner plates. We're not exactly into beating them...
Treats were great to teach our older dog to come, sit, and do parlor tricks, but useless to teach her obedience in adverse circumstances.
Her natural drives are very strong, and they're not always compatible with the human world, nor can "treat training" always deal with them (i.e. between getting a half-pound of filet mignon and trying to kill the neighbor's cat, she wouldn't choose the steak.)
A lot of trainers do have you try the thing on yourself first. They feel like "e-stim" used by physical therapists.
E-collars are
not for beating your dog remotely! They have a place, though, if and only if used properly.
Unless you're calling people like Ronnie Smith lazy or something...
