You've pretty much validated my plan. I think I'll continue to take him for short wandering walks in the early morning, short training in the early afternoon, short walk in late afternoon and another training session before supper. I never planned on taking him with (oops a I slipped a little Minnesota in my message
on one of my 2 hour + jaunts. Unless he would ride in my all-terrain jogging stroller with my 3 year old.
I asked the vet I use when I'm in this area and he said the dog will let me know when he's tired, right . . . when I'm 3 miles away from the RV and have to carry him back?? Not!
