Cameron Diaz turned compassionate action hero last Saturday afternoon when she took in an injured German Shepherd Dog.

“Cameron and a friend were involved in returning an injured dog to its owner,” Diaz’s publicist Brad Cafarelli confirmed to People.

Cafarelli said the “What Happens in Vegas” star came across the injured dog and took it to her Hollywood Hills home. Diaz cared for the dog while her assistant made Found Dog notices and posted them in the area.

“Diaz brought the dog in her house and gave it some food and water,” a source told People. “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.”

The owner took the dog to the veterinarian, and Diaz “made time to visit the vet where the dog was being treated,” the source added.
