Zak Anderegg found an starving, dehydrated puppy in the bottom of a slot canyon.

It must have been then luckiest day in this poor dog’s life. Zak staged a rescue on his own and saved Riley-the-puppy’s life.

Zak has just put together a video from that rescue. It’s hard to imagine that the puppy in the video who was too weak to stand is the same dog you see today.
