Found on the desert planet
Tatooine,
dewbacks are large lizards used by the locals as mounts and beasts of burden. These flat-toothed creatures can be found hauling goods for merchants or moisture farmers, pulling Podracer parts to starting grids, or serving
stormtrooper patrols assigned to the planet's Imperial garrison. A dewback is able to withstand the heat and dust that often leads to mechanical breakdown in modern high-tech conveyances.
