Oh, well every training method is different-doesn't make them wrong-just different, and we all don't have to agree with those methods. Every dog is different too - some respond better to some types of methods than others-Tyr responded best to soft spoken, no hit training.
He had 2 different trainers as a pup, one I left because I thought she was too rough and he did not respond well to her. he was a very timid pup. (you wouldn't know that now) Our second trainer was a man, which he responds better to anyway, and he believed in "soft handed" training. He never raised his voice, was against choke collars, and didn't even need treats most of the time. He was wonderful. Tyr did really well in his class, and i learned alot from him.
His biggest suggestion was-always work with what your dog loves, and take that away when they are bad. It could be a toy, treat, belly rubs, long walks whatever makes them happy is the best rewards. Taking away your presence is the worst possible punishment. Walk away-go in another room or just leave the house for awhile.
Just suggestions. Like I said -what ever works for the individual and your dog-we don't all have to agree.
