Jack Russell Terrier
If you remember the show Frasier then you remember his pet Jack Russell Terrier, named Moose. These dogs were bred to take on foxes and vermin underground. If these doggies get bored or are not properly socialized then they get a bit dangerous. They also never back down from a fight no matter who the opponent.
