What do you have? I seem to remember two of them were a bit of everything?
Lexie, a lab mix and the alpha -- she's the youngest at about 5 1/2.
Belle, a purebred golden retriever -- she turned 6 last Saturday.
Maya, a mostly Australian shepherd (grandparents on one side have an odd breed in there) and the alpha wannabe -- she's the eldest at about 6 1/2.
