It's easy to forget that animals can have feelings that closely resemble those of humans. But cows can have best friends, dogs are slavishly loyal to their owners, lions have close-knit family packs and dolphins work together in pods to hunt food and protect one another. Whether we realize it or not, animals are more like us than they are different.

That certainly is true for the horses featured in the video below. Watch as Arthur is reunited after four years apart with the two horses with whom he was raised as a foal, Harry and William. As soon as Arthur enters the paddock, the other two gallop over, thrilled to see their childhood friend. If this doesn't bring a smile to your face, you must be made of stone! Let us know in the comments if you've witnessed such a strong bond between or among your own pets, and share on Facebook to put a smile on your friends' faces!
