Who's really the lucky one? Looks like it's Zac Efron
"I've got a dog named Puppy," Efron Tweeted
on Friday. "He's an Australian Shepherd."
"Here's the photo of Puppy I promised earlier," he wrote
, sharing a shot of himself holding puppy in front of a Christmas tree. "It's from last Christmas morning. Hilarious! Cheers & thanks again!"
In 2005, when Efron was 19, he told Seventeen
that his dogs were "crazy. They're always getting into some kind of trouble ... but then again, they're my most loyal friends."
