Watch This Polar Bear Pet A Dog In What Appears To Be The Ultimate Display Of Friendship

"The bear then just started gracefully petting the dog like a human."

Update: This is likely a predator-prey interaction and the dog's owner's motives have been called into question following reports that one of his dogs was eaten by a polar bear last week.

There's nothing like an unlikely animal friendship to put a smile on our faces.

On a bus tour through Canada, David de Muelles stopped the tour when he noticed a polar bear sitting beside a dog, petting the dog on the head.

"This big bear had just woken up from a cat nap and stopped right by the dog," de Muelles told ABC News. "The bear then just started gracefully petting the dog like a human."

In a video uploaded to YouTube, the polar bear strokes the top of the dog's head as the dog sits calmly, staring out into the distance, probably wondering what it all means — the Earth, the universe, everything.

"It was a beautiful sight to see, and I just can't believe an animal that big would show that kind of heart toward another animal," de Muelles added in an article from CBC News

Whether the polar bear had any idea what it was doing or not, the little act of a kindness was a big, beautiful thing. Check out de Muelles' video below:
