Another thing you can do that you can do at any time, is simply walk into her. Don't knee her-it can hurt her AND you. When she gets in your space without your permission, just walk into her and calmly tell her "Back up", or off, or whatever you choose for your command. Don't say anything else to her, don't use her name. You only give the command and walk into her. When you walk into her, you may make contact with her body with yours, but it will be just like you're bumping into someone. If she jumps again, walk into her again. Try your best NOT to use your hands on her. She will see this as a reward, even if you're using them to push her away. You need to stay neutral, and when she finally stands at your side/feet, lean down and praise her. When you're on her level, she doesn't have to jump up to see your face to tell you how much she loves you. Reward her when she has four on the floor, never when she only has two. Puppies jump up to greet mom when she returns, that's all she's doing. Her new mom is just a bit taller! This is a simple solution that most anyone can do, other than little kiddos. I have taught all but my very youngest child to do this to our bouncy dog. He still bounces, but respects their space and doesn't touch them when he bounces, which for me is acceptable.
