Justin Bieber Urges Fans To Adopt Pets In New PETA Campaign (VIDEO)

Not sure if you seen all the horrible things at happen at puppy mill's across the U.S. but it's really bad and we are happy to report Justin Bieber is using his publicity to help urge others to adopt from a shelter. So now Biebs' recent hit single "U Smile" not only has his legions of fans smiling but also has homeless dogs wagging their tails and homeless cats purring. Justin shot a public service announcement called "Animal Can Always Make U Smile" for his pals at PETA promoting adoptions from animal shelters.

"It's really important that people adopt,"

said Bieber.

"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."

Approximately 8 million unwanted dogs and cats enter animal shelters every year in the U.S., and half of them must be euthanized simply because there aren't enough good homes.

Justin Bieber joins a growing list of celebrities-including Lea Michele, Kellan Lutz, P!nk, Sean Kingston, Kelly Osbourne, and Travie McCoy - who have teamed up with PETA to help animals.
