Now you can watch #4 through the rest "dog chasing a squirrel" which is really cute,

or put in search box PTSD and watch the videos about PTSD--I like the doggie dressed up as a squirrel better..giggle

The PTSD ones explain EMDR, show therapists handling flashbacks in therapy with clients, and have clips about Complex PTSD, and any other questions you may have about PTSD--lots of info here.
