It was a real dog day afternoon for some patrolmen in Las Vegas Monday.
Surveillance video shows a dog shutting down US Route 95. After the pup escapes, video shows it running amok on the road.
The pooch even began running in the opposite direction of traffic; where drivers had already slowed down to see what was going on.
People are seen sprinting after the animal, which finally ran down an off-ramp.
No word yet on what happened to the dog after it ran off the highway.
