We had Gordy for 6 or 8 weeks before we ever heard him bark.
He will probably never be great at playing with other dogs. He prefers to play with us. He is well-socialized enough to be around other dogs, at the park or in day care. Otherwise for him it is usually enough to sniff a little and then move on if he decides there is no threat. If he feels like another dog is getting too much in his space, he will but them with his hip or warn them off, but he's really not one to initiate play.
We've talked about maybe getting a second dog when he is much older, but that is a few years away.
