For the first time we consider an actual pet as a pet. In this case it is Goodboy Bindle Featherstone of Quirm, also known as Errol the swamp dragon from the Guards! Guards! Discworld novel by Terry Pratchett (one of our favourite books!).
And why wouldn't you want a badly run alchemical factory the size of a small dog as a pet?
OK sure, he flames backwards and generates sonic booms in flight... but that honestly sounds like an "other people" problem, don't you think?
Remember, whinny if you love dragons!
