Whippet
From Tardis Wiki, the free Doctor Who reference
Whippets were both strong and needed to be fed.
The Tenth Doctor described John Mark's legs as being as thin as pipe cleaners, yet surprisingly as "strong as a whippet". (TV: Fear Her)
In a parallel world, Donna Noble called a woman "Vera Duckworth" and told her to "go and feed the whippets". (TV: Turn Left)
