Thanks all for the responses! and sorry, I think my original post was a little bit defensive and misleading. Humans feelings and safety are my primary concern, so much so that at times I feel like I should never bring my dog hiking at all, because so many people seem to have bad experiences with them and don't like them there. That being said, I am working extremely hard to train my dog incredibly well, so that we'll never have to face these problems. Everything I can think of for both trail and social training, we're doing. My primary goal for him is to work in Outdoor Education with me, a teacher, and my elementary school students, so he has to be very well behaved all of the time. I think where my concerns are coming from is feeling like hikers don't want dogs on the trail at all, and my anxiety that even if I have the best trained dog in the world, I am still going to receive a lot of dirty looks/flac for having him there with me.
