Daggit

From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide

A daggit is a canine-like animal used as a domesticated pet, watch animal, or tracker. No daggits survive the Cylon holocaust.

Boxey loses his daggit, Muffit, to the destruction on Caprica.

A robotic counterpart similar in appearance to a daggit, named Muffit II is built by Dr. Wilker and presented to Boxey (Saga of a Star World).

Like a real daggit, the new Muffit proves its bravery and dedication to protecting humans during a dangerous fire aboard Galactica (Fire in Space).

Additional mechanical daggits are briefly seen in the pilot episode of Galactica 1980.
