I voted for Abby, but, given that she is a herding dog, I figured I go look up who the first Miss Rodeo Canada was. In 1955, the Connie Ivins was the first woman to hold this title. http://www.canadiancowboy.ca/inthecorral/feb-mar08.html
No idea if you will like the name or not, but thought you'd might like the idea where you could get some ideas. She's cute btw.
