There’s a couple of tame dingo’s that hang around the airport ... keeps the rats and smaller critters away ....
I bet those dingos did keep the small stuff out. Mine would attack every intruder that sucked oxygen. We have death adders and a type of monitor lizards. They all died quickly. They also kept out bad guys. One time I arrived home on my motorcycle just as a group of locals were going by. It wasn’t a nice gang, not really outlaws but not trustworthy either. Anyway, as I stopped to open the gate, I was accosted by one demanding money. He started to follow me in. I yelled for my gardeners to turn the dogs lose. The bad guy didn’t stay.
I live on the Papua side of New Guinea in Sentani. If you look for airport DJJ, I live about 1.5 kilometers away. I know, trips through don’t often happen. Just keep it in mind if you’re in the neighborhood. I hope to go back at any time in the new year. I’m here in the states due to the economy. Long story.
