The New Guinea singing dog or New Guinea Highland dog is an ancient (basal) lineage of dog found in the New Guinea Highlands, on the island of New Guinea. Once considered to be a separate species in its own right, under the name Canis hallstromi, it is closely related to the Australian dingo. The dog is relatively unusual among canines; it is one of the few to be considered "barkless", and is known for the unusual "yodel"-like style of vocalizing that gives it its name.

The New Guinea singing dog is known for its unique vocalizations that resemble a yodel. Initially considered a separate species, it shares a close genetic relationship with the Australian dingo. These dogs are rare and often studied for their primitive characteristics. While they can be difficult to train, they are highly intelligent and have a unique bond with humans.
