He swats at the doorstop with his paw and watches it vibrate with a perplexed look on his face

As it vibrates he gets nervous and moves away from it a little bit.

He hits it again and then opens his mouth while leaning away as if it’s going to attack him.

The puppy looks away from the spring for a few seconds before he turns back, realizes the perplexing object is still there and lets out a tiny yelp.

The video was filmed in Denver, Colorado, on Monday.
