For over 50 years Siberia's Institute of Cytology and Genetics has been breeding a population of foxes, selecting for tameness. Over the generations they've become increasingly dog-like. Best of all, they're available for adoption!
Unlike dogs which are domesticated breeds of wolves, these pups are the decedents of foxes. Like wolves, foxes are also canines, but unlike wolves they were never domesticated by humans until the middle of the 20th Century through the experiments at The Laboratory of Evolutionary Genetics of Animals and the Institute of Cytology and Genetics.
