I've trained my 2 year old cattle dog mix, Abbott, with positive reinforcement techniques. He's a high maintenance, mischievous dog with an attitude...kind of what Ferris Bueler would reincarnate as in canine form. Abs requires extensive handling - walks throughout the day, play time at the dog park, training breaks. (He can "close door," play dead, shake paw, do peek-a-boo, knows "mat," can bring you his "rope," "toy" or "bone," and is currently learning "sit pretty.") Whatever your dog is like, I'm sure I can handle it!
