Good luck saying no to Justin Bieber and an adorable puppy...
The 16-year old icon has teamed up with People for the Ethical Treatment of Animals to do something about the eight million dogs and cats that are shoved into animal shelters every year. In the following PSA, Bieber says:
"It's really important that people adopt. 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."
Unfortunately for teenage girls, Bieber has posed for a PETA poster, as well. But, like many other company spokespeople, is it not naked on it. Sorry.
