It's called "College Dog" and it's something that took me a little over three hours to write out.
The idea for the story came about while checking out one of the Yahoo Groups I visit. A guy did a series of morphed photos of himself changing into a dog and wanted to see if someone could do a story based on the pictures. After looking over the photos, which were quite good by the way, I came up with a storyline and typed it out.
I'm quite proud of this little story and, as an added bonus, I sent the story to the guy who posted the pictures and he loved it. So that's cool.
