Prepare yourselves. This is about to get teary. When Iraq veteran, Bill Campbell, came home from active duty, he was on 100% disability, having suffered severe traumatic brain injuries. Luckily, Bill was matched with Pax, a kind golden retriever service dog who helped Bill get back to living his life. Now, Pax is going back to the women’s correctional facility where he was trained to be a service dog by one of the inmates herself. Watch their emotional reunion and keep some tissues on hand.
