According to Scientific American, Hewitt was lucky enough to capture one of the only photographs of the shy canine creature.
At first, Hewitt had no idea what he had taken a photograph of. When he realised how special it was, he contacted Tom Wendt, founder of New Guinea Singing Dog International.
"The only place a pure New Guinea singing dog could possibly be found would be in the remote highlands where the natives rarely visit and, due to the lack of humans present, a domestic dog would not thrive," said Wendt.
“This is exactly where Tom and his team were when the dog was sighted and photographed.”
Papua New Guinea is the second largest island on Earth and contains approximately 8% of the world's terrestrial and aquatic species.
Still, its native dogs are hard to find. In the mid-1990s, a team spent almost an entire month searching for one to breed.
The island is divided into the independent Papua New Guinea and the Indonesian-controlled West Papua.
Hewitt states that the native dogs prefer to roam around West Papua, which is less populated and highly forested - perfect conditions for being kept alone.
The last time a photo was taken of the New Guinea Singing Dog was in 1989 by an Australian mammalogist and paleontologist.
It is because of these rare photos that scientists can conclude wild dog populations still exist.
