Yeah, I still lurk around here. So much good advice!
I can't help but reply to this. I started my B-mix out with a supposedly "positive only" trainer for his first class. Really, it was positive rewards and positive punishment, and made my dog more reactive. I think he also picked up on my discomfort with screaming at him, yanking the collar, etc. After the conclusion of that class (I regret not trusting my instinct and just quitting), I joined this forum, in hopes to understand my dog better because I saw that he was not responding to traditional training methods.
I also found this video:
We started with that, and now my dog knows at least 20 commands/tricks. Our relationship is 1000% improved, even if he still has some quirks. This youtube trainer (channel name Kikopup) has videos for teaching everything, and how to do it with no intimidation. In my horrible collar correction class, I had a dog heeling, head down, eyes glazed over. Who really wants that???? I now have a happy, tail-wagging, heels-before-I-ask dog because he associates heeling with rewards and praise.
Sorry for the huge post, I just had to bump this up.
