Just a small example I thought I'd share. Most people walk their dogs off leash on our trail. But one couple insists their dog is too scared and leashes him up when they see another dog, or he's on the leash already. He's not that small, a Soft Coated Wheaten. A few years ago the man followed my suggestion to let the dog off and he and Oban had a great time running up and down the trail and through the mud puddles. The poor dog was not clipped at the time and he looked like he'd gotten into the gulf oil spill but he had fun. Last week I met the lady for the first time and as soon as she saw us she put the poor dog back on the leash. He was hiding from me and Oban and Oban wasn't even looking at him, all Oban did was walk by and this poor intimidated dog hid behind his owner when my dog passed on the other side of the trail. I told her, "They've met, they play together." and she let him off. Less than one minute later her dog was offering play bows to mine. Maybe a bit extreme and it's a good example. I do have another recent encounter where the leashed dog brought out the bully in the off leash dog. What about the rest of you? Any similar observations of the difference in behaviour leashed and off leash?
