Dave

Daves are the name of canines who have become police dogs. They become police dogs at the age of one (or seven in dog years). They appear in the Smithsnorian Museum in Wario: Master of Disguise. When Nigel B. Whistlebottom spots Wario in a room, he will blow on a whistle and call some cops. A Dave might also come in the room when Nigel blows on his whistle. Daves are unbeatable but can be knocked out for a few seconds before fighting again.
