Bandersnatch

The Bandersnatch is a character in Tim Burton's 2010 film Alice in Wonderland. It appears as a dog-like creature under control of the Red Queen. It is large, with a barrel chest and fore-paws that are quite dexterous. It's covered in pale, shaggy fur with dark gray spots and has a somewhat flat (but not pug) face, with a wide mouth that has multiple rows of teeth and a long tongue. It also has a long tail. It doesn't speak, but seems at least somewhat intelligent. Evidently, it has venomous (or otherwise poisonous) claws, wounds from which will 'putrefy' unless treated by someone with evaporating skills- barring that, they may also be treated with the saliva of the Bandersnatch itself.
