Yeah, sorry - people on YouTube were screaming abuse....
Yeah, animals can play rough - they're domesticated beasts... I'm not saying you should throw them around, but they are incredibly tough. My dogs are Boston Terriers, and they're a smaller breed, but man - you should see the acrobatics they do!
Old Dogs, of course, like to just curl up and sleep a lot. And I like to pet their heads and back as they do.... heh. My friend has a 15 year old mutt, who just loves to lay around. I envy him. He's quite awesome.
