I wouldn't call that crazy...I would say maybe overly friendly, but not crazy. Trust me, I would rather have an overly friendly pooch than an anti-social one. Ask Edwina's Secretary about our overly friendly poochies!!

I know that there are ways to train them not to jump, but I've been too lazy to do it! lol

Good luck. I would suggest a training book or calling a professional trainer for their suggestions.
