Does Major walk along with you well on leash? Once he's
learned to accept leash walking without to much trouble, he
then should learn "heel", or walking at your pace & in the same
direction as you. Sounds more complicated than it really is. I
hope you can get some clear instructions & help from the booklet
or from someone who can explain it better than I can.
Good luck with the training. Major is such a cutie.
