Jasmine is a social butterfly, who can't seem to comprehend why any person or dog wouldn't want to say 'hi' and play with her. While I think it's great that she's so well socialized, she feels the need to say hello by jumping up on people. Even though most people claim they don't mind, she shouldn't be doing it, and as she's getting quite big, one good jump could easily topple a small child. We've been trying to teach her 'down' from day one, but she either doesn't get or just refuses to obey, as it almost never works. I was wondering if anyone had any good recommendations that I might try out.
