VIDEO: Boy with Rare Muscle Disorder and 3-Legged Dog Become Besties

Owen Howkins, 8, has a rare muscle disorder and was afraid to ever leave his house. That was until he met a 3-legged dog named Haatchi.

Owen's health condition, called Schwartz-Jampel Syndrome, causes his muscles to always be in a state of tension. This not only causes Owen pain and discomfort, but made him feel self-conscious when strangers would gawk at him. All that changed when he met Haatchi, an Anatolian Shepherd that lost his leg in a train accident while tied up to a railway line.

After being rescued by the RSPCA, Haatchi would end up in the home of Owen's family and they quickly became the best of friends. Owen and Haatchi now go everywhere together.

Even more inspiring, the confidence in Owen has grown and grown over the last year — all thanks to Haatchi.
