Gnasher is a black dog (an "Abyssinian wire-haired tripehound") who first appeared in issue 1363, dated 31 August 1968. He has extremely strong teeth that can leave teeth marks in seemingly anything and enjoys chasing postmen. His name comes from the British slang for teeth (gnashers), which in turn comes from the French ganache meaning "jowl", a word also used in chocolate manufacture. In the first-ever Dennis the Menace strip, the family also had a pet chihuahua, who has not since appeared.
