"A lot of animals are getting abused in different homes," Justin says. "...And I think it's really important that we just stay aware about these situations."
Starring with a papillon puppy named Bijoux, Justin talks about his own dog, Sam, and how he entered the Bieber family. "We moved to a city where we didn't really know anybody, so I kind of wanted a friend around. And Sam was kind of like that friend," he says.
