So, one of the stories I would LOVE to read is a post-movie fic about Clint and a therapy dog.

Backstory: My mom is a therapist. We had a dog when I was a kid who had TERRIBLE separation anxiety. An Australian Shepard mix. After he ruined all the rugs, my mom decided to try and take him to the office with her. Shep was an AMAZING therapy dog. For one thing, he was a herder, so once he learned the patients, he would go and get them from the waiting room and bring them to the office for his treat.
He was also completely chill, and would just sit next to a patient, or sleep on the floor. Unless someone cried, then he'd go and lick their fingers.
And some people, reluctant to talk for whatever reason, would open up to the dog rather than my mom.

I guess I imagine Clint having a chance to interact with a dog like Shep, and the therapist noticing. So she gets him a retired military dog (http://www.save-a-vet.org/d7/adopt) and they proceed to heal each other.

(The dog hates thunderstorms, so Clint stays up all night, sitting in the bathtub with him. Clint has trouble getting up, and the dog pesters him cause it needs a walk, making him go outside. Just, a mutually beneficial relationship.)
