That migraine was a real head-banger and my typing was atrocious! I just want to correct a couple of things. It's not hee, it's heel. And you don't use the Halti the same way as you use a prong collar - I meant that you should use it as GENTLY. A Halti will usually prevent the dog from pulling in the first place, but if Rock is stubborn, be sure not to yank his head around as it could cause injury. If he's REALLY stubborn, you can give it slight yank straight back.

There were two other things I neglected in my first post. First, don't repeat commands. If you're positive he knows what the command means, it shouldn't be said more than once. To get him on the right track, put him on his leash to give him commands (I'm guessing you mean sit, down, etc.?). Just think of it this way. You give him a command and he ignores it. Then you say it again and he complies. The next time, you end up having to say it three times - and so on and so on... He needs to respond the first time, even if it mean you place him into the position you want. As for him trampling over the little dog, that's a tough one. Rottweilers just don't seem to realize that they're big and strong. The best solution to that is working on your obedience training with Rock so he'll respond to your instructions.
