What seperates your dog from someone else's?

What separates my fur brat from other dogs? He's a well disciplined hybrid wolf dog. He never barks, he howls with wolves when we go bush camping and he loves our kids. Never bitten anyone, never bares his teeth, never growls (outside of adults wrestling and play growling) and has an awesome sweet and gentle disposition. His furry little lips are also permanently suctioned to hubby's left butt cheek! lol (in other words, he's hubby's suck, he loves hubby - they buddies all the way)
