When the volunteers from the shelter found 2-year-old Cheech they all were scared at first because of the face this dog was making. To them, it seemed like he was snarling in fear as he was a street dog who has spent most of his years living off the streets. They weren’t sure of how he would react when coming in contact with humans. Later, at the shelter when Cheech was flashing his confusing grins they found out that he was actually smiling. This smile was soon viral all over the internet.
