Some wolves may have dog in them. As the nation’s chief propagator of the legend of the arboreal basset hound, this gives me hope.

WASHINGTON – Today’s dogs are descendants of ancient wolves. Now, it turns out, at least some of today’s wolves inherited traits from ancient dogs.
Gray wolves have that name because of their color, but in North America many of them have dark or black coats instead of the standard gray.
The genetic mutation producing dark coats appears to have occurred in dogs, and then spread from them to wolves when the species mated, according to researchers led by Gregory S. Barsh of Stanford University.
