Yeah, my Bella is a jumper! We're working on it, trying to teach her "four on the floor" before she gets attention. She's just trying to reach your "muzzle" so she can kiss you because she's submissive.
It would be much easier if people wouldn't squeal and engage her behavior as cute. It quickly turns from cute to super annoying.
I was born to be a pessimist. My blood type is B Negative.
