Itâ€™s really true what they say: dog really is manâ€™s best friend. Joey was diagnosed with autism when he was young and struggled with making friends. Feeling lonely and isolated, Joey wasnâ€™t doing very well â€“ that is, until his mom decided to get him a dog. When Joey was introduced to his new best friend, a sweet pit bull named Roxy (who was dealing with her own struggles as well), neither of their lives would be the same. Watch their incredibly sweet journey below and make sure you have some tissues on hand.
