the same derivation, is primarily of North African stock and is a separate breed. Health Lifespan In various surveys conducted within the UK, Afghan Hounds were shown to have an average lifespan of about 12 years, similar to other breeds of their size. In the 2004 UK Kennel Club survey, the most common causes of death were cancer (31%), old age (20%), cardiac (10.5%), and urologic (5%). Those that died of old age had a median lifespan of 12 years, with 12% living to at least 14. Health concerns Major health issues are allergies, cancer, and hip dysplasia (not typical of bakhmulls). Sensitivity to anesthesia is an issue the Afghan Hound shares with the rest of the sighthound group, as sighthounds have relatively low levels of body fat. Afghan Hounds are also among the dog breeds most likely to develop chylothorax, a rare condition which causes the thoracic ducts to leak, allowing large quantities of chyle fluid to enter the dog's chest cavity. This condition commonly results in a lung-lobe torsion (in which the dog's lung twists within the chest cavity, requiring emergency surgery), due to the breed's typically deep, "barrel"-shaped chest. If not corrected through surgery, chylothorax can ultimately cause fibrosing pleuritis, or a hardening of the organs, due to scar tissue forming around the organs to protect them from the chyle fluid. Chylothorax is often fatal. Among other health problems are laryngeal paralysis, dilated cardiomyopathy (twice as common in males as females), and dermatological issues such as testosterone-responsive dermatosis of male dogs (often seen in castrated males), nasal depigmentation (also known as Dudley nose), and skin tumours. Afghans are also prone to Central diabetes insipidus (CDI), hypothyroidism and tricholemmoma, a rare condition which mainly affects older dogs in the Middle Ages. Ocular conditions that can occur include medial canthal pocket syndrome (breed predisposition due to shape of head), corneal dystrophy, cataract and generalized progressive retinal atrophy (GPRA). Afghan myelopathy (causing pelvic limb ataxia) is sometimes reported. In popular culture Pablo Picasso said that his 1967 statue located in Chicago's Daley Plaza represented the head of an Afghan Hound named Kabul. The Afghan hound has been represented in multiple animated feature films and TV shows, including Universal Pictures' Balto (Sylvie), Disney's Lady and the Tramp II: Scamp's Adventure (Ruby) and Hasbro Studios's Pound Puppies (Twiggy). An Afghan hound also appeared in the movies One Hundred and One Dalmatians, 101
