Tingroom Radio—驯服宠物（中）

 Amazingly, after only ten years of selected breeding, the team had developed a strain of foxes with dog like tameness towards humans: tail wagging, face licking, playful friendliness¹. But that’s not all. Although the scientists always selected foxes based only on behavior, the tame foxes have several other traits that differentiate² them from wild foxes. Traits including: white patches of fur on the face, the loss of the fox’s strong musky odor, wagging tails that curl up over the back, drooping³ ears and dog like barks and whines⁴.
