She needs someone her own size/age. That pup is a baby and she could accidentally hurt him. I would have more controlled visits maybe when he gets a little bigger and not let her get all ramped up around him.
It's the same when I let Lakota play with the kitten, I have to make sure things don't get too ruff.
