Sometimes you just have one of those days.

You're out of coffee, you've got a flat, and then you find yourself being chased by police. It happens to the best of us, including this little dog.

The scene is the San Francisco Bay Bridge on a typically foggy day. There are no cars on the bridge, due to police blocking off traffic, except for a motorcycle cop and a police car. They're in hot pursuit of a fleeing chihuahua. RELATED: See Images of the 2015 Ford Police Interceptor

The little dog is running for all he's worth while the police follow along at a safe distance. You never know when a chihuahua is suddenly going to lose his cool, turn, and attack like a wild coyote. There's no word on how the dog got loose, but he's lucky he was spotted and that the police gave him an escort. He wouldn't stand a chance on that bridge if it was full of traffic. Thankfully, once he got to the other side, he was safely returned to his owners with one heck of a story to tell the other dogs in the neighborhood. RELATED: Dog Chews Through UK Man's Aston Martin
