@RiiSi totally agree with you on your leash point. To clarify, curly is chesty in introductions which could be seen as aggression to other dogs so I don't let him run and introduce himself. So instead the leash is loose when he meets other dogs and I have him sit. I agree with you that a tight leash can also be seen as a target to other dogs so when they get into the butt smelling part of intros I let go of the leash.
