We just learned about the type of dog called Chow Chow.
Another type of dog is called the Basenji.
Basenji's are from Africa, and they are a very old type of dog going all the way back to the ancient pharoahs. There are paintings of these dogs sitting at the feet of pharoahs from over a thousand years ago.
The basenji's bark is different, and sounds more like a yodel or is sometimes called a barroo.
