Why aren't there Chihuahua-based Superheroes?

I watched Spiderman tonight and, frankly, it raised more questions than it answered. For instance, why does the Green Goblin aim his hover craft at Spiderman when he's standing right behind it? Why do all the students at Peter Parker's school look 30? Did the directors get product placement fees for everytime Spiderman said "Uncle Ben"?

However, in my mind the most pressing question is this: Why SPIDERman? Why not Chihuahua man? There is a distinct lack of Chihuahua-based superheroes coming out of Hollywood, and frankly, I'm quite disturbed. While Chihuahuas have made great strides in Tinsel Town, the Taco Bell dog and Bruiser from Legally Blond are little more than token Chihuahuas, placed to appease the Chihuahua-American lobbyists.

Think of the awesome superpowers Chihuahuaman (or, in the interest of being gender inclusive, Chihuahuawoman) could have? Why he (or she) could be quite small in stature, yet extremely loud! He could menacingly growl at things! He could have the amazing ability to sense when a piece of food is about to land on the floor! He could raise his hackles and scare away Doberman-man. The possibilities are limitless!

I call upon Hollywood to cease its breedist ways! Stop type-casting Chihuahuas as small dogs and start putting them in real roles! Forget about spiders and bats -- they are animals any Chihuahua could take anyway! Chihuahuas are where it's at.
