Yesterday I was talking about how to keep a dog from jumping on you. Don’t encourage it in the first place. If you already have then you have to expect it. When the dog jumps on you just gently put it down and say no, or walk in with something, like a bag and put it between you. After you are in and the dog didn’t jump on you, then give it about 3 minutes of praise and playing with it, maybe a treat.
