A daggit is a dog in the science fiction television series Battlestar Galactica. Like Earth dogs, they served as a domesticated pet, watch animal, or tracker; none survived the Cylon holocaust.

In the 1978 pilot, Saga of a Star World, Boxey (Noah Hathaway) loses his pet daggit, Muffit, in the Cylon attack. Boxey is given a replacement pet, a robotic daggit named Muffit II, which made a regular appearance in the original series. Muffit II was portrayed by a trained chimp named Evolution (“Evie”). Muffit does not play a role in the 2000s revival of Battlestar Galactica, where it appears that at least one dog survives the Cylon attack on the colonies.
