CIRCUMSTANTIAL EVIDENCE

Why you shouldn't rely on it:

Scenario 1
Circumstance: out for a walk with the big dogs.
Evidence: Nacho trots along "like a true champion!"
Finding: Nacho is leash trained.

Scenario 2
Circumstance: out for a walk by himself.
Evidence: Nacho lays down and drags through the snow like a plow.
Finding: Nacho is a sled.

But he's such a cutie, and still light enough to be carried when you're in a hurry!
