my question is also about jumping, not on myself, but my grandson. all he has to do is start to run or walk fast and she jumps, she is still young and wants to play. he is her size on 31/2, so i think she is mainly playing, no aggression at all. i have tried loud happy sounds to call her and treat her if she comes, and a whistle, works for a bit, but as soon as my grandson runs again she is right there, hasn't knocked him down, but her nails have scratched, and always her feet are at the face. any suggestion would be appreciated.
