Your dog will eventually figure it out, but it's unfortunate that you're not both using the same words for the same commands - since you've only had him for a few months, it's going to make things harder for him. But best of luck with your DH...it sure didn't work here, lol. Off/Down, Quiet/Enough, on and on. It was frustrating! The rough play is fine, IME. I play rough with my dogs but they never mistake that private play with general good times with others.
