My current adventures with Max have me looking for a faster, effective way to teach him to stop mouthing people's hands and arms and to stop jumping on them. I'm not a fan of the "remote collar" and I'm not putting in enough time or being consistent enough for positive reinforcement to nip this in the bud quickly. I use some of Cesar Milan's techniques (like entering and exiting before allowing the dog to do so), but others (like rolling him when he makes teeth to skin contact) seem to make him behave aggressively.
Today, I picked up a business card belonging to a trainer who uses the many of the same techniques as Milan. Coincidently, I also came across this funny skit by comedian Charlie Murphy on The Dog Blog. (Murphy does use profanity, so consider yourself warned,). While the clip is meant to be funny and exaggerate the things shown on Milan's show, it does serve as a reminder that this type of training is not based solely on positive reinforcement.
