The Domesticated Silver Fox is the result of nearly 50 years of experiments in the Soviet Union and Russia to domesticate the silver morph of the Red Fox. Notably, the new foxes not only become more tame, but more dog-like as well: they lost their distinctive musky "fox smell", became more friendly with humans, put their ears down (like dogs), wagged their tails when happy and began to vocalize and bark like domesticated dogs. The breeding project was set up by the Soviet scientist Dmitri Belyaev.
