I've created and provided a mock-up of a potential Canine PTSD Symptom Scale. Scroll down and click on the pdf link below. This is not an accredited diagnostic tool. It's designed primarily for my own research purposes, and to satisfy my intellecutal curiousity. If you're interested in looking at it, please feel free to do so. .
This is just a preliminary document. I'll be making changes as I get feedback from dog owners, veterinarians, dog trainers, and behaviorists.
