Thanks for the feedback. My husband actually suggested that I was being just stubborn. Can you believe it?
I have no intention of backing down as Max won't be wearing a training collar. Since Max already knows most of what is being taught at puppy class I had already planned on using it as socialization and a chance for him to be able to work with lots of distractions. I'll admit we haven't walked much because the weather has been terribly frigid. Regardless of this he did very well walking on the harness. I know a lovely trainer who Mindy takes agility with. Her puppy classes weren't convenient for me but we will certainly carry on with her after this as her philosophies more closely match what I think Max needs.
