Service animals can be a needed resource for many people, including wounded military veterans. A school in Fulton County got a special visit from a military veteran who read a new picture book to students about his late service dog.

What does it mean to be a hero? That's the subject of "A Bridge Named Amos," a new picture book written by Retired Army Sgt. Rick Yarosh and illustrator/elementary school teacher Kevin Cannon. It's about Yarosh's service dog, Amos, who helped Yarosh through injuries he sustained while serving in Iraq in 2006.

“He was my icebreaker. He was my bridge to the connections that I have today and meeting these kids and doing these things, I probably wouldn't have been doing them if I had never had Amos,” said Yarosh.

The book tells the story of a labrador retriever becoming a service dog and helping Yarosh overcome nervousness about speaking to children at schools.

“The biggest takeaway is Amos was my hero because of the things that he did for me. And in the simplest terms to a kindergarten or first grader, that's what a superhero does. They help other people and if they can realize they can help other people too, then they can be superheroes as well,” said Yarosh.

“I thought it was going to be a challenge because of how Rick looked. And the characteristics, the facial features now, and he's just like ‘Dude, just draw me; I'm not going to be offended,'” said Cannon, a teacher at OESJ Elementary School.

Yarosh’s superhero Amos helped him through 100,000 miles of traveling while encouraging kids across the country. Amos passed away in October, shortly before his 14th birthday.

Yarosh says he carries Amos with him in his heart to every visit he does at schools. Because of the help Amos provided Yarosh during his life, he won’t be needing another service dog. However, Yarosh is hoping in the future to write more books about Amos.
