This is an amazing breed and it is very rare. The NGSD is a wild, primitive breed that is in danger of becoming extinct. At the moment, I am the ONLY breeder and I would love to see more interest in this breed. I am currently on my 3rd Generation (they turn 1 this Sunday) and I am willing to sell my 4th Generation back up pups for cheap if there is someone who is interested in becoming a New Guinea Singing Dog (NGSD) breeder. :3

* First got the attention of the scientific community in the 1950's.
* Unlike any other dog species, singing dogs have a unique structure at the back of their mouth that may help them make some of their unusual sounds. 
* Sonograms show the howl of a singing dog is similar to the song of the humpback whale.
