Basenji


The Basenji is a breed of hunting dog. It was bred from stock that originated in central Africa. Most of the major kennel clubs in the English-speaking world place the breed in the hound group, specifically in the sighthound type. The Fédération Cynologique Internationale places the breed in its group five, and the United Kennel Club places the breed in its Sighthound and pariah group.
The Basenji produces an unusual yodel-like sound, due to its unusually shaped larynx. This trait also gives the Basenji the nickname barkless dog.
Basenjis share many unique traits with pariah dog types. Basenjis, like dingoes, New Guinea singing dogs and some other breeds of dog such as Tibetan mastiffs, come into estrus only once annually, as compared to other dog breeds, which may have two or more breeding seasons every year. Both dingoes and Basenji lack a distinctive odor, and are prone to howls, yodels, and other vocalizations over the characteristic bark of modern dog breeds. One theory holds that the latter trait is the result of selecting against dogs that frequently bark, because barking could lead enemies to humans' forest encampments. While dogs that resemble the Basenji in some respects are commonplace over much of Africa, the breed's original foundation stock came from the old growth forest regions of the Congo Basin, where its structure and type were fixed by adaptation to its habitat, as well as use.

Lineage

The Basenji has been identified as a basal breed that predates the emergence of the modern breeds in the 19th century. Recent DNA studies based on whole-genome sequences indicate that the domestic dog is a genetically divergent subspecies of the gray wolf and was derived from a now-extinct ghost population of Late Pleistocene wolves, and the basenji and the dingo are both considered to be basal members of the domestic dog clade.

Name

The Azande and Mangbetu people from the northeastern Congo region describe Basenjis, in the local Lingala language, as mbwá na basɛ́nzi. Translated, this means 'dogs of the savages', or 'dogs of the villagers'. In the Congo, the Basenji is also known as "dog of the bush". The dogs are also known to the Azande of southern Sudan as ango angari. The word basɛ́nzi itself is the plural form of mosɛ́nzi. In Swahili, another Bantu language, from East Africa, mbwa shenzi translates to 'wild dog'. Another local name is m’bwa m’kube m’bwa wamwitu, or 'dog that jumps up and down', a reference to their tendency to jump straight up to spot their quarry.

History

Originating on the continent of Africa, basenji-like dogs are depicted in drawings and models dating back to the Twelfth Dynasty of Egypt. Dogs of this type were originally kept for hunting small game by tracking and driving the game into nets.
Europeans first described the type of dog the Basenji breed derives from in 1895—in the Congo. These local dogs, which Europeans identified as a unique breed and called basenji, were prized by locals for their intelligence, courage, speed, and silence. An article published called The Intelligence of Dogs by Stanley Coren, PhD questions this. It ranks the breed at #78 out of 79, which is the second to lowest rank in intelligence. Some consider this an unreliable list, as it focuses on only the ability to listen to a first command. Some consider independent dogs such as Basenjis and Afghan Hounds more intelligent than obedient breeds because of their ability to recognize which actions benefit them, and which simply please another.
Several attempts were made to bring the breed to England, but the earliest imports succumbed to disease. In 1923, for example, Lady Helen Nutting brought six Basenjis with her from Sudan, but all six died from distemper shots they received in quarantine. It was not until the 1930s that foundation stock was successfully established in England, and then to the United States by animal importer Henry Trefflich. It is likely that nearly all the Basenjis in the Western world are descended from these few original imports. The breed was officially accepted into the AKC in 1943. In 1990, the AKC stud book was reopened to 14 new imports at the request of the Basenji Club of America. The stud book was reopened again to selected imported dogs from 1 January 2009 to 31 December 2013. An American-led expedition collected breeding stock in villages in the Basankusu area of the Democratic Republic of Congo, in 2010. Basenjis are also registered with the United Kennel Club.
The popularity of the Basenji in the United States, according to the American Kennel Club, has declined over the past decade, with the breed ranked 71st in 1999, decreasing to 84th in 2006, and to 93rd in 2011.

Characteristics

Appearance

Basenjis are small, short-haired dogs with erect ears, tightly curled tails and graceful necks. A Basenji's forehead is wrinkled, even more so when they are young or extremely excited. A Basenji's eyes are typically almond-shaped. Basenjis typically weigh about and stand at the shoulder. They are a square breed, which means they are as long as they are tall with males usually larger than females. Basenjis are athletic dogs, and deceptively powerful for their size. They have a graceful, confident gait like a trotting horse, and skim the ground in a double suspension gallop, with their characteristic curled tail straightened out for greater balance when running at their top speed. Basenjis come in a few different colorations: red, black, tricolor, and brindle, and they all have white feet, chests and tail tips. They can also come in trindle, which is a tricolor with brindle points, a rare combination.

Temperament and behavior

The Basenji is alert, energetic, curious and reserved with strangers. The Basenji tends to become emotionally attached to a single human. Basenjis may not get along with non-canine pets. Basenjis dislike wet weather, much like cats, and will often refuse to go outside in any sort of damp conditions. They like to climb, and can easily scale chain wire/link fences.
Basenjis often stand on their hind legs, somewhat like a meerkat, by themselves or leaning on something; this behavior is often observed when the dog is curious about something. Basenjis have a strong prey drive. According to the book The Intelligence of Dogs, they are the second least trainable dog, when required to do human commands. Their real intelligence manifests, when they are required to actually "think".
Basenjis are highly prey driven and will go after cats and other small animals.

Health

There is only one completed health survey of dog breeds, including the Basenji, that was conducted by the UK Kennel Club in 2004. The survey indicated the prevalence of diseases in Basenjis with dermatitis, incontinence and bladder infection, hypothyroidism, pyometra and infertility.

Longevity

Basenjis in the 2004 UK Kennel Club survey had a median lifespan of 13.6 years, which is 1–2 years longer than the median lifespan of other breeds of similar size. The oldest dog in the survey was 17.5 years. The most common causes of death were old age, urologic, behavior, and cancer.

Fanconi syndrome

, an inheritable disorder in which the renal tubes fail to reabsorb electrolytes and nutrients, is unusually common in Basenjis. Symptoms include excessive drinking, excessive urination, and glucose in the urine, which may lead to a misdiagnosis of diabetes. Fanconi syndrome usually presents between 4 and 8 years of age, but sometimes as early as 3 years or as late as 10 years. Fanconi syndrome is treatable and organ damage is reduced if treatment begins early. Basenji owners are advised to test their dog's urine for glucose once a month beginning at the age of 3 years. Glucose testing strips designed for human diabetics are inexpensive and available at most pharmacies. A Fanconi disease management protocol has been developed that can be used by veterinarians to treat Fanconi-afflicted dogs.

Fanconi DNA linkage test

In 2007, the first linked marker DNA test was released for predicting Fanconi syndrome in Basenjis. With this test, it is possible to more accurately determine the probability of a dog's carrying the gene for Fanconi syndrome.
Dogs tested using this "linkage test" return one of the following statuses:
This linkage test is being provided as a tool to assist breeders whilst research continues towards the development of the direct Fanconi test.

Other Basenji health issues

Basenjis sometimes carry a simple recessive gene that, when homozygous for the defect, causes genetic hemolytic anemia. Most 21st-century Basenjis are descended from ancestors that have tested clean. When lineage from a fully tested line cannot be completely verified, the dog should be tested before breeding. As this is a non-invasive DNA test, a Basenji can be tested for HA at any time.
Basenjis sometimes suffer from hip dysplasia, resulting in loss of mobility and arthritis-like symptoms. All dogs should be tested by either OFA or PennHIP prior to breeding.
Malabsorption, or immunoproliferative enteropathy, is an autoimmune intestinal disease that leads to anorexia, chronic diarrhea, and even death. A special diet can improve the quality of life for afflicted dogs.
The breed can also fall victim to progressive retinal atrophy and several less serious hereditary eye problems such as coloboma, and persistent pupillary membrane.
