A person wearing black athletic pants and green Adidas sneakers steps onto a metal-slatted floor, opening a glass door to reveal a small, brown and white Jack Russell terrier standing on the pavement outside. The person briefly pets the dog, then steps back inside, leaving the door slightly ajar. The dog stands outside, peeking through the gap in the door.
