Justin Bieber is on board with PETA’s campaign to adopt pets rather than purchase them.

According to People for the Ethical Treatment of Animals, roughly 8 million dogs and cats enter animal shelters every year in the United States.

“It’s really important that people adopt,” Bieber says. “I really encourage going out to an animal shelter or a place where you can get a dog who has been abandoned or doesn’t have a home.”

The Biebmeister filmed a PSA for PETA as well, sharing his story of adopting his dog, Sam.

“We moved to a city where I didn’t really know anybody, so I kinda wanted a friend around.”

Bieber joins a long line of celebrities who have posed, many often nude, for PETA campaigns. Khloé Kardashian, Pamela Anderson, Paul McCartney, Eva Mendes, Pink and Mark Ronson, to name a few, have been featured in previous PETA ads.
