Aly is right with the Gentle Leader! It was a life...err, arm saver for my family with our great dane. Only a few times wearing it and she had the walking thing down pat.

During my recent obedience class, we were learning heel. In order to teach this method, we would take an entire chicken-based hot dog in our hand and hide almost all of it within our palm. Only a little piece should be sticking out. Hang your arm and your side and walk. The hot dog should keep Amber's nose near your legs. You should slowly be able to remove the hot dog once she gets the idea that walking next to you gets rewarded. It is a long process and you have to be careful with your fingers because they could get "nibbled". I wouldn't recommend that your mom do this exercise until Amber is adjusted to it.

You can certainly work with Amber, even if only on the weekends, but your mom needs to try and do something too. Otherwise, your mom will be PART of her pack, and YOU will be the leader. Not good for Monday-Friday when you're not there. I definitely think that an obedience class would be helpful and fun for both Amber and you mom!

Best of Luck!
