Jesse Vasconcelos suffers from severe Post Traumatic Stress Disorder and traumatic brain injury, after serving overseas in Iraq.
A few weeks ago, Vasconcelos received a service dog named Chance.
He says without Chance, he felt like a prisoner in his own home.
"They're remarkable animals, they're there for us; we're able to talk to them," Vasconcelos said. "They understand us as we feel no one else does."
Chance and Jesse have been side-by-side ever since they met almost four weeks ago.
