I’m looking for this story about a creature—I think it was in the 1930s—who lived on a farm with a family somewhere in the US. Its name was something like “Greif” I believe, and it claimed to be very intelligent. There’s a photo of it too.

Anyone?

EDIT: Solved. VERY fast. See the comments. Thanks @today-pepperland-goes-bluey and @mybloodiedvalentine.
