- Midge is a scruffy, unkempt gray poodle of the miniature variety and has long schnauzer-like fur bristling the end of his muzzle and over his eyes. He is a toy poodle breed, making him very small and his eyes appear to be ruby red in colour. A matching red collar with an upside-down paw-print shaped pendant hangs from his neck.
- Midge has shared a character settei and official artwork with Pumpkin.
- Midge most likely gets his name from his small size. Either in relation to the insect by the same name or the derogatory term for someone with dwarfism.
