I’m afraid I’m not going to be of any help, but I can sympathize, I too have a jumpy hound and nothing I do can make her stop. When I first got her she would jump on guests, that has stopped and now she saves her Jump Around routine for me when it’s time for a walk. Like you, I’ve tried all the normal things to get her to stop and also like you nothing works. She’ll stop if I stop moving but the second I move she’s back at it. She knows “go to your bed” but it’s totally useless when she’s in that state of mind.
I feel like I’ve tried everything, but I’m curious what else all the smart folks here have to say.
