A guy in Argentina posted a video of a dog that slipped and fell into some river rapids while it was trying to get a stick. Then another dog grabs the other end of the stick as it's going by, and pulls the dog up onto a rock.
The guy says they play there all the time though, and the dog wasn't actually in any danger. And it looks like the other dog was really just trying to get the stick, not save his friend.
Where there goes that lol
