Agree with the Cesar Millan thing ^ if you watch a few of his shows, you will see.
I learned a lot from him and still am.
I must say... I bought the Premier Easy Walk harness and it has helped SO much! 99.9%
of the time, Jackson just walks right beside me, very calmly, and I never even have to
look down to check on him. I used to have a harness that attached on the back and
it made him become a sled dog. Ever since I've gotten this harness, since the moment
I put it on him, he's been an angel to walk! And he's 7 mo. old right now.
