Missing dog travels 400 miles

A dog that disappeared from a Los Angeles home three and a half years ago has been found, in Phoenix, Arizona.

The dog's owner, Crystal Keys, was astonished to get a call that her black and white mongrel Bosco had been found in Phoenix and identified by his microchip. When Bosco went missing, Keys realised he had no collar or tag but he did have the identifying implanted chip. She called the company that handles the chips but heard nothing back, until now.

No one yet knows how the dog travelled the 400 miles to Phoenix.
