Jethro is having a very bad day with his anxiety. Quinn invited some new friends to cheer him up. PTSD dogs are either fight or flight babies. Jethro is flight. Which means he is fearful of everything unfamiliar and will flee to get away from things that scare him. Which means someone either a. he becomes a sled dog trying to get home or b. his muscles freeze up and he gets carried home. Then someday he is actually afraid to cross the threshold of the door. Other days all is right in his world and you would never know he has PTSD.
