It was a dog day afternoon for Cameron Diaz
, who took in an injured German shepherd Saturday afternoon.
"Cameron and a friend were involved in returning an injured dog to its owner," Diaz's rep Brad Cafarelli confirmed.
The actress, 35, cared for the dog at her Hollywood Hills home while her assistant posted notices about the found canine.
"Diaz brought the dog in her house and gave it some food and water," said a source. "Her assistant posted a 'found German shepherd' sign and [the dog's owner] – Diaz's neighbor who was driving around the area – came across it."
Later, the owner took the dog to the vet, and Diaz "made time to visit the vet where the dog was being treated," the source added. Reporting by PERNILLA CEDENHEIM, JULIE JORDAN and MARY MARGARETRELATED ARTICLES:
