This touching PSA from Argentina shows the amazing bond between a man and his dog, but it has a twist ending that hits you when you least expect it.

The purpose of the PSA is to increase awareness of organ donation. At any given time, there are over 100,000 people waiting for an organ that can save their life. And since each donor can save up to 8 lives, it's easy to see why Argentina wanted to create this PSA to spread awareness.
