When she’s not busy saving lives on TV’s “Grey’s Anatomy,” Katherine Heigl spends some of her spare time saving dogs, as Access Hollywood recently showed its viewers.

Heigl and her mother, Nancy, recently teamed up with Pup My Ride, an animal rescue program from the Best Friends Animal Society, to rescue dogs from shelter life.

“Over 600 dogs have been saved and adopted,” Heigl told Access Hollywood.

“Up in Utah and Arizona and some of these states around California, they have waiting lists for small dogs, people wanting to adopt and here we have an overwhelming number in the shelters,” Heigl said.

As a result, Best Friends drives the dogs, which would otherwise be put down, to new, out-of-state homes.

Heigl was tempted to take one home herself — but didn’t. She already has six, the latest being a dog she and her husband, Josh Kelley, found in a trash can in Mexico.

“Someone had literally thrown him out, and he was probably at the time, three or four weeks old,” she said. “He was just this teeny tiny, fit-in-the-palm-of-my-hand, and Josh said, ‘I think we should take this one home,’ and I said, ‘OK! I’m dying for a puppy.’”
