How can I say this without seeming like an idiot? Um, I can't, lol. I actually taught my puppy to act like a maniac on a leash. Yep, starting at 8 weeks old, he was always let out to do his business on a flexi. He learned that tension equals freedom, and that he could roam wherever he wanted to. I trained him very well - if I ever need him to cart things around, he's perfect!
