Fido was a male nonsentient dinosaur of unclear species.


This large and aggressive dinosaur was somehow alive in 214,200 B.C. to be tamed by Scrooge McDuck's distant ancestor Muk-duk, who made the beast of "guard-dog" of the cave where he kept the equivalent of his descendant's fortune, namely a large supply of cured fish.

Behind the scenesEdit

Fido appears in the 1975 story The Deep Sea Deed.
