I rescued Roxy from our local humane society, and although they had her labeled as a "Shepherd mix", I'm skeptical. I know the GSMD is a relatively uncommon breed, but Roxy does follow the temperament of a GSMD very closely. She is currently 53lbs at 6 months of age, and 21" tall. She is very stocky (see her profile pictures). She adores my children and my cat especially. Any opinions on whether or not she might indeed be part GSMD?
