Leeson (Madame Vastra)
From Tardis Wiki, the free Doctor Who reference
Leeson was a performer in Henry Gordon Jago's Monstre Gathering, performing The Faithful Hound. (PROSE: Madame Vastra)
Behind the scenes
The Doctor's robot dog, K9, is voiced by John Leeson. Given the name of the poem, this is a clear homage.
