This man sent me an email after I took his photo:

“I suffer from documented clinical Post Traumatic Stress. I have been a victim of mistaken identity and was shot as a teen. I won the case, but left emotionally scarred. It makes me nervous to be outside at times. 

My wife read about how dogs help Soldiers with PTS and got me a dog, Roscoe. Apparently, there were many clinical studies that support this…I am thankful she is a smart lady. 

Roscoe makes me feel more confident to roam the New York streets again. He provides an Emotional support for me. I have three boys and they can see me strong when I am outside thanks to Roscoe.”
