New Guinea’s breed of “singing” dog was found again in the wild after 50 years until 2016, when an exploration found and studied 15 wild dogs in Papua. Another exploration in 2018 was conducted and the team of researchers gathered specimens to check if these wild dogs are the predecessors of the singing dog breed. There are only about 200 New Guinea singing dogs in captivity and none had been seen in the wild for half a century.

This rare breed is known for their howls and are even similar to the calls of humpback whales. “The singing dog’s howl sounds like a yodel, with the tones going up and down. And when in a group, one dog starts singing and others join in at different pitches, each with its own unique voice,” according to San Diego Zoo. The researchers are hoping that more wild singing dogs could reproduce in their natural habitat.
