Georgie tries to jump up on the couch if I am sitting there and then when I go to pick him up he runs. He does this with everyone, and my neices Yorkie Oliver did this as well when he was a puppy. I think it's because they want you to chase them
Usually when he does that I get someone else to sneak attack him and put him up with me or I get on the floor with him and play
I think it's just because Buttercup is a puppy it's not you at all. Oliver doesn't do that anymore and George doesn't do it as often. Don't worry I am sure he is not scared he is just a baby and will come around.
