The dingo is a domesticated dog, that has gone wild for a second time. Their ancestors came from Malay Archipelago, an island group between the main land of Southeast Asia and Australia. The dogs have weird taste preferences and are even prone to eating other dingoes. This is a unique feature of the dingo, since this kind of behavior in the animal kingdom is only seen in cases where animals suffer from hunger.

The relationship between humans and dingoes has been quite complicated. The dogs used to hunt the local sheep in Australia, which forced farmers to put out traps. But even this measure didn’t help to save their sheep. That’s when humans decided to build a 3,488 mile-long fence as protection from dingoes.
