I'm reading one book where the protagonist has a psychic bond with her pet, one that helps with hunting and scouting, and some fighting. (Snowdenaelikk and Briel).
So I started remembering older books with the same kind of pet connection: Flinx and Pip (1983-), Honor and Nimitz (1992-), Gillian and Pyewacket (1958 movie), for examples.
How far back does that go in science fiction and fantasy works? I know that familiars will feature heavily on the fantasy side so I'm hoping to shed some light on the science side, too.
