This can be dangerous because they can get stepped on
aside from being as annoying as hell
when he comes over and starts barking and growling Stop .... don't keep walking
because the moving target is what he's playuing with
and you say NO!
when you have his attention resume walking .... but shuffle you feet
this will serve two purposes
It will push him aside
and keep you from accidentally stepping on him
keep repeating this same scenario everytime he barks and/or bites
