VIDEO: Police struggle to catch-up with runaway chihuahua

THEY may be tiny, but boy are they fast.

A tiny chihuahua has found itself in the midst of a low-speed pursuit across the four-land Oakland-San Francisco Bay Bridge in the United States.

Police and animal control teams attempted to capture the rogue pup on April 3.

The dark-coloured dog even stopped a few times, almost as though it was teasing its pursuers.

Authorities discovered no identifying tags on the dog, which has now been taken to an animal shelter.

Its escapade earned it the nickname Ponch.
