My girl Hailey is small, but really muscular---so much so that she looks really comical when she walks, and has to sit side-saddle. I had her at the track vet one day, and all the old racing guys were ooh-ing and ahh-ing over what a good-looking girl she was. The funny thing is, she was the only pup from her litter that DIDN'T make it as a racer!
