Labradoodle you are not alone! My Bella is a 7 1/2 month old standard poodle whose main fault right now is jumping up on company. She does not do this to people living in our house but when newcomers come she gets soooo excited. This of course is very embarrassing and annoying. One of the things we were told to try was to bend the knee as she is advancing towards you. This does not allow for her to get close enough to really be able to bounce up. Like your dog, she is a different dog when the choker chain is on and obedience training is going on. It's like that little silver necklace is magic. I am sure that constant reinforcement will find us winning this battle but it certainly is frustrating at times!
