Hmm, I appreciate the feedback from everyone. I thought he sounded a bit over the top on some issues, and don't agree with everything he says, which is why I wanted some opinions.

So, do you have favorite training methods? I've taken basic classes with Star & clicker training with Rosie (which I hated), Sherman was an angel & didn't need further training, but I need a little help with Jack. He's pretty well behaved overall, but there's a weird dynamic going on between him & Star. He's very headstrong, competitive, and the biggest problem is that he is aggresive towards smaller dogs at the dogpark. It could just be very physical rough husky-style, but it's hard to say. The little dogs don't think so, they freak out. So I haven't been able to let him run off-leash to burn off some of that energy.

I have contacted a couple local trainers but haven't heard anything back yet. Thought if I found dvd's of some good lessons on basic training it would help me cope with him better.
