“…The congenital malformation of Rhodesian Ridgebacks and their crosses popularly referred to as a "cystyy was first described in Great Britain by Hare (1932) who suggested that it resembled trichostasis spinulosa in man. Steyn et al (1939) described the condition independently in South Africa and originated the term dermoid sinus which is now generally accepted.…”

“…Microscopical examination showed that the dermoid sinus is a tube of skin containing hair follicles and sebaceous glands so that the lumen contains both hairs and sebum. Hare (1932) described the longitudinal section of a dermoid sinus from an 1 l-monthold pup and Steyn et al (1939) described the cross section of a sinus from a 9-monthold pup. Breeders of Rhodesian Ridgebacks destroy pups affected with dermoid sinus as soon as the condition is detected, being encouraged in this by their club rules.…”

Abstract—The Rhodesian Ridgeback is a modern breed having been standardized in 1922. It originated in South Africa by crossing Hottentot dogs with various European breeds. The breed has one defect, a congenital malformation, generally known as dermoid sinus. The authors have investigated the inheritance of the condition and, contrary to the hypotheses of others, suggest that it is a simple recessive character. The implications of this are discussed. Réslamé—Le chien de Rhodesie, dénommé Ridgeback, est d'un élevage récent, bien établi depuis 1922. II est originaire d'Afrique du Sud, résultant d'un croisement de chiens Hottentots et de divers chiens européens. Cette souche a un défaut, une malformation congénitale généralement désignée kyste dermoide. Les auteurs ont recherchés l'hérédité de cette condition, et contrairement à d'autres hypothèses, ils suggèrent qu'il s'agit d'un caractère héréditaire récessif. Les conséquences en sont discutées. Zusammenfassung—Der Rhodesische “Ridgeback’ ist eine neuzeitliche Zucht, die im Jahre 1922 standardisiert wurde. Ihr Ursprung ist in Sued Afrika, vollzogen durch Kreuzung von Hottentotten Hunden mit verschiedenen europaeischen Rassen. Der “Ridgeback’ hat einen Fehler: eine congeni‐tale Missbildung, die allgemein als “Dermoid Sinus’ bekannt ist. Die Autoren haben die Vererbung dieses Zustandes untersucht und schlagen vor, entgegen den Hypothesen anderer Autoren, sie als ein einfaches, recessives Merkmal zu bezeichnen. Die sich daraus ergebenden Beziehungen werden eroertert.

“…The origin of the breed is unknown. It has been suggested that several different European dog breeds (Table 1) and the Hottentot hunting dog, an indigenous breed of Africa from which the characteristic ridge originated, have contributed to generate the modern Rhodesian ridgeback breed (Hare 1932, Lutman 1966, Hawley 1984).…”
