Loved it!
Steve does a GREAT dog voice. He sounds very similar to Dug in Pixar's UP. Or I should say that Dug sounds like him, since this story pre-dated the release of that movie. "I don't know you, but I love you!" If I hadn't had that association, I probably would've pictured Bull as a German Shepherd, but I pictured him as Dug. Seriously, if they ever make an UP sequel and the original Dug voice actor gets sick, they should give you a call.
I'm definitely a dog person, so there wasn't much chance I'd dislike this story. The title would've sucked, coming from anyone but a dog. But it shows his enthusiasm, his priorities, gives a hint that he's a cop, gives a quick synopsis, and sets up the tone of the story all in one. Likewise the constant profanity would've been annoying from anyone but this character. His partner wanted him to use the word, so he does, all the time, regardless of its appropriateness like a kid showing off his shiny new knowledge. I loved the loyalty and the enthusiasm he showed about everything.
The comment at the end about the Marx story was great. Did Ragtime ever submit a story to EP? I hope he does, that one itself was pretty much a kickass flash story as-is.
I thought the name Terry Stringer could have been more subtle, but that's really my only quibble, and so minor that it's only worth mentioning to show that that's really all I could find to complain about.
And, since someone set the precedence of posting a dog picture, I'm going to have to go dig out one of my three pups. Back soon...
