Audrina Patridge, star of MTV’s The Hills, has joined forces with PETA by posing in a new ad encouraging animal lovers to adopt furry friends from shelters and rescue groups rather than purchasing from breeders or pet shops.

“I wanted to get involved with PETA because I’ve always been passionate about animals, and I think this is a great way to make people and all my fans aware of all the animals that need a home. And a lot of people go to pet stores and breeders to buy their animals, but you should adopt, so go to an animal shelter and rescue a dog,” Audrina says.

The ad reads: “Buying animals means killing animals… Each year, six to eight million unwanted dogs and cats are turned in to shelters, and half are killed because there aren’t enough good homes.”

Joined by her own rescued pooch, affectionately dubbed Speedy Gonzalez, Audrina also urges pet owners to spay and neuter their cats and dogs to prevent unwanted births.
