I know with larger dogs, you can give them a knee to their chest to make them not jump, but with these little guys, I think maybe you should put a leash on them when you know someone is coming over, and when they get there just make sure if they jump up you can sorta pull back on the leash. That sounds harsh, but I'm sure it will work. You could also tell your guests to just ignore your pet when they first walk in, and let them calm down before saying hi to them, or maybe, just have them turn their backs if your dog jumps, sometimes when they don't get paid attention to, they stop! Good LUck!
