Thanks for all the compliments! She really is an awesome little dog, especially for what I want to do with her (I adopted her partly because I wanted to get involved in dog sports, especially agility).

The only thing I find at all questionable about the Boston guess is that she's pretty big for a Boston cross at 35 pounds, but I suppose she could have been crossed with something bigger. Regardless, she's down as a Boston X on all her paperwork--living in an apartment makes that a much more, ah, useful guess than "pit mix" for me!
