Q: What a dog likes to chew?

A: Oh you know dogs, they'll chew on just about anything: a bone, a Frisbee, your wingtips. When it comes to chewing, dogs don't discriminate.

Now that's most dogs.

Old Odin here ain't most dogs. He's got a highly refined sense of smell; only one things sets him off and gets him chewing like that:

The smell of freshly harvested human organs about to be sold on the black market.

I'm going to need you to open your suitcase, sir.
