We have a schnoodle - now too old to hike very far, but she was a great hiker in her day. She has long legs for a small dog and loves people. They're known for being friendly. Ours is normally TOO friendly, but the exercise of mountain climbing usually calmed her to the point where she was perfectly fine. I called her the trail "social director." Her wagging tail and insistence at saying hello to everyone seemed to be asking folks if they were having as grand of time as she was out there.
