I would take him with you. Not so much for the bonding issue. I think eventually they will work it out. But you'll worry all weekend and I think it's good to socialize him more. I wish Calvin wouldn't freak out when we have to go in the car/carrier. I'd love to take him out and about sometimes but all he's ever known is this apartment. If Jax likes "vacationing" I would encourage that.
