They say it is a trait common to all French herding dogs, news to me.
This doggie had not only dewclaws on all four feet (which I am told is rare), but on the hind legs, there were double nails. Like this:
This dog was related to the dogs of the people who lead my horse riding tour in Cappadocia, Turkey.
The ride wound all over a relatively small area (at our furthest point from the ranch, one could have ridden straight home in an hour) for a week, spending a couple nights here and a couple nights there. The ranch dogs would accompany us, and then, they’d be gone. “Where’s the dog?” “Oh, he got bored and went home.”
So, no surprise that one of their puppies was living at a pension they use regularly.
