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 (9% of responses), incontinence and bladder infection (5%), hypothyroidism (4%), pyometra and infertility (4%). 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.
