Facebook honcho Mark Zuckerberg just adopted a super-cute little puppy dog ... that LUCKY son-of-a-bitch.
As TMZ previously reported, Mark and his girlfriend Priscilla Chan had been in the market for a Puli for a while -- and finally found one in Oregon. They even created a Facebook page for him.
The couple named the puppy Beast. We were hoping he would have gone with Bark Zuckerberg.
