Basenji
A Basenji might look cute and harmless, but they are hunting dogs. They originated from central Africa, and one of their most unique attributes is their larynx that allows them to give off a yodel-like sound. Their yodeling is out of the ordinary, so people call them the barkless dog.
They have distinct wrinkles on their forehead, so you might think they’re always confused about what’s happening. These dogs can easily get attached to one person, but they tend to get shy when strangers are around. Basenjis won’t be the best choice if you have other non-canine pets in your home.
