No, Canis Lupus literally means 'Grey Wolf.' So he was calling Cain a dog and his mother a bitch.
Ohhh thanks
I think it's a joke. Because canis means "dog" in latin and lupus means "wolf" (again latin), so he's called Dog Lupus, and bitch in english also means "female dog".
:)
so Lupus... Yahwi knows about Cain's family? Since he said he's a son of a bitch...
