Pug faces off against robot counterpart. Guess who wins?

A pug dog called Bishop in Portland, Oregon, faces off against a miniature robotic dog.

Bishop is initially wary and jumpy, and sniffs and barks at the mechanical creature, before bolting.

"We had just moved to Portland from Wisconsin, and Bishop's grandma (my mom) had sent with him a new buddy who I unboxed for him and set up on the floor," said the filmer. "This was his first reaction to it. He still has similar reactions even now when I bring it out."
