Morgrahound

Morgrahounds were creatures not unlike wolves. Cleaver had two pet morgrahounds called Heracles and Broteus, whom he kept aboard his HS Sun Turbo 500 and were both killed in 1639. (AUDIO: The Galileo Trap)

In 1906 San Francisco, the Eighth Doctor encountered Sam Sonora's barking dog and said that he had met better-tempered morgrahounds. (AUDIO: The Gift)
