Basset Hound

Known for their impeccable sense of smell, this hound may have little legs, but lots of stamina. As with many dog breeds, the basset t hound is steadfastly loyal and playful. Just what you need for a Patronus.

“The Patronus is a kind of positive force, a projection of the very things that the Dementor feeds upon - hope, happiness, the desire to survive – but it cannot feel despair, as real humans can, so the Dementors can’t hurt it.”
