I have PTSD. Im a vet and can have pretty bad panic attacks and what the doctors call psychotic episodes. The happen when I wake in the middle of the night. I have almost torn apart a 400 dollar tent before. I found using a nite ize spotlit so if I wake up and start to freak out I realize where I am. My dog was a pet first then I found out the training is free. It was a bit of a hassle because she is a pitbull and they though pits are to high strung. They normally use labs. She learned faster than any of the other dogs
