Glarosus
From Tardis Wiki, the free Doctor Who reference
The Glarosus was a shrieking creature kept in the zoo on board the Dalek battlecraft. The Daleks intended to isolate its insane hatred to be bred into Daleks that would be cloned in the New Earth System. K9 Mark II released it from its cage and it turned against its Dalek captors. (COMIC: Doctor Who and the Dogs of Doom)
