We've heard several times that a dog is a man's best friend. Their unconditional love is beyond awesome. Proof is this story of two dogs that affectionately help each other go thru life.

Lily is a Great Dane that was struck with a rare medical condition when she was young. This sadly caused her to lose both of her eyes. She is now almost 7 years old and for more than 5 years her best friend Maddison, also a Great Dane, leads and guides her everywhere. They walk closely together, almost touching, so she knows which way to go.
