Also, no to both questions IMO…no to another dog right now (you’re having problems with one, don’t multiply that. Get this one under control first), and an adult class won’t help. Get one on one help from a trainer FIRST, and use classes as a way to up your training once his fear is under control.
Don’t push “socializing” this dog by forcing him to meet everyone and play with every dog he sees. It’ll backfire.
