Holly, I think you're a Super-Mix dog. You've got the best qualities of all the 3 dog breeds that are in you.
And you sure are a happy girl! You look so wonderfully relaxed in the pic. Truly, you're an inspiration to all of us to chill out a bit! I'd like to put your pic on my work desk to remind me how to relax.
Congratulations on becoming Dog of the Day.
