Very unique names.
Make sure you spend plenty of one on one time with each puppy. Don't let them get too attached to each other, they need to bond with you and they need to favor you over each other.
I would also train them separately and crate them is separate rooms so they don't get too attached.
Also, same sex aggression can occur in this breed, you may or may not have issues between them in the future that can result in really bad fights.
