Teazel
From Tardis Wiki, the free Doctor Who reference
Teazel was Edward Lunn's pet dog. While out hunting in September 1909, Teazel and Lunn were captured by Zygons, who used their body-prints to assume their appearances.
Teazel's appearance was taken by Brelarn, warlord of the Zygons. After being rescued, Teazel guarded Edward and his family. (PROSE: Sting of the Zygons)
