Riley the dog is a bit of an adrenaline junkie.
How do we know this?
Because he followed his owner into an airplane... and then followed his owner out of that airplane before it landed!!
A homeless man named Lauri da Costa walked into a hospital in Brazil after a random attack, and left his dog outside - expecting to return after a few hours.
However when doctors at the Passo Fundo hospital discovered that the man had melanoma on his face, they opted to go through with surgery immediately.
When the homeless dude was finally able to receive visitors, the hospital staff set up a very special reunion, and the emotions going on are enough to make one's heart burst with love!
Still, Lauri da Costa will have to remain in the hospital for a little while longer, but his doggy poo isn't going anywhere - the best friend is back to waiting outside for the man!
This is one case where we think the hospital's rules against pets were made to be broken!
Check out their emotional reunion video (below) with lots of licking!!!
