Read the text about singing dogs.

One dog begins howling. Others join in. Some of the howls are high, and some of the howls are low. So, when a group howls together, it can sound like singing. These unique sounds are made by New Guinea singing dogs, and they are quite different from the sounds other dogs make.

New Guinea singing dogs live in the mountains on the island of New Guinea. However, they are very shy and rarely seen. They look a lot like other kinds of wild dogs, but in some ways, they are more like cats. They are great climbers and jumpers, and they groom themselves often to stay clean. Their eyes shine green in low light, just like cats’ eyes do. These catlike singing dogs are one of a kind.
