I keep my dog on leash because she is not good with other dogs. For that reason, I do not appreciate it when off-leash dogs run up to us, and the owner yells, "Don't worry, he's friendly!" I typically yell back, "Yeah, but my dog's not!!" It creates a very stressful situation, for both me and my dog. Along those lines, because of my dog's issues with other dogs, I do not take her camping or hiking in very heavily populated areas. If we do not see another dog all day, that is perfect. I am aware of her limitations, and I try not to expose her to situations in which she is uncomfortable or likely to act crazy.
