An unaccompanied and injured dog limped into a hospital in Farmington, New Mexico:

When the automatic doors at San Juan Regional Medical Centre's emergency room slid open Saturday night, the pooch walked in, blood on his nose and paw, and a puncture hole in one leg, according to The Daily Times newspaper.

Animal control officer Robin Loev responded to a call from the hospital and suspects the puncture wound was from the bite of another dog.

Loev says the German shepherd mix appeared to be intelligent and calm - and knew enough to go to the right place.
