Basenji

The Basenji is a breed of hunting dog that was bred in Africa. Most of the major kennel clubs place the breed in the Hound Group; more specifically, it is in the sighthound classification. The Basenji does not bark like a typical dog would but produces an unusual yodel-like sound commonly called a "barroo", due to its unusually shaped larynx. It has been given the nickname of "barkless dog".
Basenjis have many unique traits. Basenjis, like dingos, come into heat only once annually, as compared to most other dog breeds which usually have two or more cycles every year. Both dingos and Basenjis share a trait of lacking a distinctive odor.
Basenji are small, short-haired dogs with erect ears, a tightly curled tail and a graceful neck. A Basenji's forehead is wrinkled, especially when the animal is a puppy or a senior citizen. Basenji eyes are typically almond shaped, which gives the dog the appearance of squinting seriously. They usually weigh around 25 pounds and stand 16 inches tall. They are structure is as long as they are tall. Don't let size fool you, the basenji is an athletic dog and is powerful. They have a graceful gait like a trotting horse, with their usually curled tail straightened out for greater balance, when running flat-out at their top speed.
The Basenji is alert, energetic, curious and reserved with strangers. The Basenji is somewhat aloof, but can also form strong bonds with its owner. They typically are one person dogs. Basenjis may not get along with non-canine pets. Basenjis dislike wet weather, can easily climb over chain wire fences, and are very clever at getting their own way. The Basenji has the unique property of cleaning itself like a cat. It can be described as frisky, tireless at play, and teasing the owner into play. Some will even stand on their hind legs when curious about something. Most Basenji problems involve a mismatch between owner and pet so it is important to understand all the characteristics of a Basenji before attempting to own one.
