In 2002, a study looked at 2 fossil skulls of large canids dated at 16,945 years before present (YBP) that had been found buried 2 metres and 7 metres from what was once a mammoth-bone hut at the Upper Paleolithic site of Eliseevichi-1 in the Bryansk region of central Russia, and using an accepted morphologically based definition of domestication declared them to be "Ice Age dogs".

Maxillary canines begin to calcify by 4 months of age. The enamel of the tooth is completely formed by around 6 to 7 years of age and the permanent maxillary canines erupt at around 11 to 12 years of age. The root is completely formed by 13 to 15 years of age. The maxillary canine teeth are slightly wider than the mandibular canine teeth.
