Prison time is hard time. Depending on where an inmate is locked up, they can spend anywhere from 21-23 hours a day in their cells, regardless of the severity of their crimes. Wherever possible, inmates who really want to get out are making the most of that time. But it turns out there is one job that is perfectly suited to someone with that much time on their hands: training service dogs for wounded veterans.

America's VetDogs employs inmates like Tyrell Sinclair, an inmate at Connecticut's Enfield Correctional Facility, to train service dogs destined for wounded veterans – and the dogs work wonders for the inmates as well. For Sinclair, it gives him something to do, something to look forward to every day. More than that, the increased attention the inmates are able to give the trainee dogs cuts the training time down to just one year instead of two to five years. "After committing a crime, being in here, you just sit around and think about how bad things are, how bad a person I am for being in this predicament," said Sinclair. "Once I got the dog and got into the program, things were better. It's like a whole different outlook."

Sinclair says he was amazed at the abilities the dogs have once they are subject to the proper training and skills. "It amazed me," he said. But it's not just the constant companionship of man's best friend that helps inmates like Sinclair through their jail time. The inmates know the dogs will not be with them for very long if all goes according to plan. It's knowing that the dogs they train are destined to help someone who served their country that gives the inmates the boost in confidence. "It almost makes me feel like a proud dad."
