The fact that Up did not talk about dog PTSD ruined it for me. After viewing the film for the thirty-seventh time I realized the fact that talking-dog Doug does not have a long discussion about how dogs have PTSD. Now that makes the film near unwarrantable to me as it should to you as in this horrible evil scene.
Why did Doug not sit down with Carl and Russell and have a long talk about the long dark road of dark despair that he must now walk, and how try as he might the pain shall never leave him? Why would they not want kids to see that?
