For when it is stated, for instance, that the German Spitz
dog unites more easily than other dogs with foxes, or that certain South American indigenous domestic dogs do not readily cross with European dogs, the explanation which will occur to everyone, and probably the true one, is that these dogs have descended from several aboriginally distinct species.
He saw Spitz run out his scarlet tongue in a way he had of laughing; and he saw Francois, swinging an axe, spring into the mess of dogs.
Spitz was the leader, likewise experienced, and while he could not always get at Buck, he growled sharp reproof now and again, or cunningly threw his weight in the traces to jerk Buck into the way he should go.
Buck received them in comradely fashion, Dave ignored them, while Spitz proceeded to thrash first one and then the other.
Like Dave, he asked nothing, gave nothing, expected nothing; and when he marched slowly and deliberately into their midst, even Spitz left him alone.
