They say a dog is a man's best friend.

In this case, this dog's best friend was another dog. Who saved his life.

The video takes place in Argentina. A black lab jumps into a river to fetch a massive stick, then isn't able to make it back to solid ground. As the dog is being pulled down the stream, his best puppy pal comes to the rescue by pulling him out of harm's way.

The dog's owner came out to let concerned dog lovers know that the stream doesn't lead to a waterfall, but to another larger pool of water.

Regardless of the danger, it's good to know that dogs are just as loyal to each other as they are to us.
