dec 24, 2004 - Belyaev's foxes are noted to be friendlier

Description:

"By 2005-2006, almost all the foxes were playful, friendly and behaving like domestic dogs. The foxes could "read" human cues and respond correctly to gestures or glances. The vocalizations they made were different to wild foxes."
