Is there any chance your dog came from Mt. Currie in British Columbia (north of Whistler)? He looks just like my step-son's dog, who happens to be what we call a "Mt. Currie Special" (semi-feral mixed breed) in this neck of the woods. I have my step-son a DNA test kit one year for Christmas and the results came back as Bouvier de Flanders and German Shepherd mix.
If you're green, you're growing...if you're ripe, you're rotting!
I try to greet the world like my pets do...boundless enthusiasm, intense curiosity and no concept of yesterday and tomorrow.
