I just brought home a 11 week old Rottweiler last Sunday. He's a big boy already. The only problem that I am noticing so far is that he likes to grab ahold of our pant legs and socks and not let go. When we tell him to drop it, he gets a little more aggressive and sometimes growls. I don't want to encourage this behavior. And I know if he continues this when he's any bigger I'm in trouble. Is it just normal puppy behavior? What would be the best way to stop it? I am enrolling him in puppy classes so we can begin to control some of his behaviors.
I've attached a photo of baby Cain.
