Pet owners warning

I checked for local trainers and found one that advertised he uses "commercial shockers" not the weaker kind that can be bought in a pet store. I don't believe in nor will I subject our dogs to pain and fear training. I guess it works but maybe it's a method to make a quick buck and I believe there are other alternatives. I don't think there is anyone here that would recommend that a dog should be beat to hurt him to train him not to whiz in the house. I found a recently killed rabbit under a tree in our yard so I went to get a shovel to bury it. By the time I got back there was another freshly killed rabbit laying beside it. I knew which dog killed them, (he's the fast one) so I called him to where the rabbits were and told him ,"no rabbits, you're bad," etc. That was about two years ago and I've seen rabbits run in front of him and he doesn't give them a second look. No more dead rabbits. We don't consider this dog the smarter of our two dogs, he's just an average mutt. I realize that if this two minute lesson didn't work there isn't a single bunny in our yard that could kill the dog. Shockless training would have to be repeated enough times to be sure the dog understood and the dog's owner should be making the commands...IMO.. It would be a lot more convenient if there was a trainer who used a snake but no pain and fear tactics but if not I'll get my own snake. It could be interesting, "I can catch that rattler, here, hold my beer".. :B
