I enjoyed this origin story of the first dog(s) (plural) which result from the bond formed between an injured wolf and a cro-magnon teen when the teen is given up for dead after falling off a cliff during a bison hunt.
My own dogs, a Havanese and a Havanese-Maltese cross, recognized the threat at first posed by the wolf on the screen and barked frantically until the friendship between boy and wolf solidified.
