Yes, because if a dog was gonna go apeshit on a person's leg, the shoe would:
a) look brand new
b) not have any blood, grass, water, or dirt on it,
and c) be completely intact
Scared panicked people don't look that close at things. They see shoe leg and dog and immediately lose their head panicking and running away when the dog just wants to enjoy his new bone in peace
My comment was a jest. I have an American Staffy that looks just like this and she is the goofiest doofus on the face of the planet, you just have to give her a sharp look and she rolls over to submit. Mind you, she does have a bit of a foot fetish - will like your toes forever if you let her.
