Richie backs campaign for 'dog urinals'

Nicole Richie is lending her name to a bizarre campaign to save street lights - from the dangers of dog urine.

The socialite, who has two dogs - Foxxy Brown and Honeychild - has signed up to promote Swedish inventor Lennart Jarrelbro's latest creation, dog urinals, to stop the metal on the posts being eroded by the chemicals found in canine waste products.
