I recently saw a lady trying to walk her energetic puppy, who was running, rolling, sniffing, and constantly straining against the leash -- everywhere except by her.  She was pleading in frustration, and yanking hard on the leash.  The puppy was either trying to pull her along as he sprinted out front, or refused to come to her when he wanted to sniff longer around a tree.  Neither she nor the puppy looked the least bit happy.
