Dingo

Dingo, originally uploaded by jsarcadia.

Australia's native dog. They're still out there in the wild but usually further north than this. There's a colony on Fraser Island (off Queensland coast) which is the purest of the lot due to no mixing with domestic dogs.
Some people shoot dingoes unfortunately. They eat livestock and have been known to attack, and even kill, humans who get too close. Personally, I think that's the humans' fault, not the dogs'. If you know it's dangerous you don't go up and try to pat it!
