We've all seen the amazing excitement that was Rio 2, right? Well, Blu's pal and everyone's favorite bird-chasing mutt Luiz is in there, but only at the beginning and the end! Ever wonder what loveable Luiz was up to for the rest of the film, aside from drooling? (It's medical condition…) Or just how he managed to travel all the way from Rio to the Amazon? Trust us, you can't possibly imagine the laughter and thrills involved! Check out A Dog's Tail. In the tradition of Rosencrantz and Guildenstern are Dead!
