LA PUENTE (CBS) — A young Chihuahua mix may need a new home after being rescued from a locked sport utility vehicle over the weekend.

Police were called about 11 a.m. Saturday to the 600 block of Ashcomb Drive in La Puente after passersby found a puppy panting inside the vehicle. The SUV was parked in the sun with its windows rolled up, said Evelina Villa, an official with the Department of Animal Care and Control.
