You've had a look at two different batches of dog pictures, and now it's time to choose your favorite among the two most popular. Will you pick Chachi, Leslie Banks's "nearsighted" Chihuahua/Jack mix, or will you vote for Darwin, the Airedale that inspired Sherry Rind's Houses Full of Laughter?

And, after much delay, I've finally come up with a prize: Alison Pace, whose Carlie ran a close second in Friday's competition, has generously agreed to sign a copy of her new novel, City Dog, for the owner of the dog that gets the most votes by 12:01 a.m. (Eastern) on Wednesday, August 13.
