When her son returned from the Marines a few years ago, Dena Coukoulis knew he was not himself and was suffering from PTSD and she needed to do something about it. Dena speaks with Loni Edwards, the founder of The Dog Agency and PetInsider, about how a video of her gifting her veteran son a dog for Christmas went viral, how the dog, Willa, has helped her son turn his life around, and how the experience led her to write a children's book about the importance of talking about your feelings.
