Shhh, it's a secret!

A black dog wearing a harness and a green collar is hanging out of the open passenger-side window of a white pickup truck, its body dangling over the side. A man in a dark uniform, possibly a police officer or K-9 handler, stands beside the truck holding a leash or tool, looking toward the dog. The scene takes place outdoors on grass with bare trees in the background under an overcast sky.
