I have been in obedience classes over 2 years now and this has not been an issue with me yet or my instructor. I have talked to many trainers which some say don't let him in your lap around others, take to all shows and around strangers to get use to surroundings, throw on back, squirt water, leave and only reward good behavior. I've heard it all and am at a lost. He's great at agility and won't be able to go to trials with this behavior.
