The story of a boy and a dog who changed each other's lives...8 year old Owen Hopkins and his 3 legged dog Haatchi.

An English boy with limited mobility formed a special bond with a three-legged dog nobody else wanted, and now their story is becoming a book.

Owen Howkins, 7, suffers from Schwartz-Jampel syndrome, a rare genetic condition that leaves his muscles in a permanent state of tension. It makes moving difficult — and also caused Owen to become fearful of meeting new people.

Until he met Haatchi the dog, Buzz60 reports. Owen's mother learned about Haatchi online. The Italian shepherd had been tied to a railroad track where he was hit, and his tail and one leg had to be amputated. Owen's family adopted the dog, and Haatchi and Owen formed a bond straight away.

In a video about the pair created by students from the University of Hertfordshire, Owen speaks about meeting Haatchi for the first time.

"The first day I met him," Owen said, "he just laid up to me and put his head on my lap. And that's what happened."

Owen continued, "He changed my life. I'm not scared of strangers now."

In an interview with TheBreeze.com, Owen's father, Will Howkins, said that within two or three weeks of Owen getting Haatchi, his son was eager to go for walks with the dog "because it was something different for other people to look at as opposed to Owen. He was gaining confidence and talking to people about Haatchi as opposed to people staring at him, and he loved it."

In 2013, the pair took first place in the Friends for Life category at the Crufts dog show in the U.K. Upon winning, Owen remarked, “I am so happy. Thank you to everybody who has voted for me. I am glad that Haatchi is in my life, because he makes me smile all the time and is my best friend.”
