Dingoes are smaller than regular wild dogs, found in packs in non-freezing biomes. Although their description would imply otherwise, dingoes are not any more prone to attacking livestock than any other natural predator. They are large predators though, and will attack dwarves. Dingoes can be hunted and then butchered at a butcher's shop for mid-value meat.

They also are just as annoying as wolves in adventure mode, and even more common, although smaller and maybe less dangerous.
