Its forebears can be traced to the semi-domesticated, [clarification needed] ridged hunting dogs of the Khoikhoi, which were crossed with European dogs by the early colonists of the Cape Colony of southern Africa. It affects Rhodesian Ridgebacks at a rate of only 0.75%. Treatment for hypothyroidism in dogs consists of an inexpensive once-daily oral medication. The Rhodesian Ridgeback is a breed of domestic dog developed in the Southern Africa region. The inclusion of However, the genetic test which distinguishes dominant homozygotes (R/R - two ridge genes) from heterozygotes (R/r - one ridge gene) is available (Health conditions that are known to affect this breed are Dermoid sinus is a congenital neural-tube defect that is known to affect this breed. "The only disqualification in the AKC standard for this breed is "ridgelessness". [1] Its forebears can be traced to the semi-domesticated, ridged hunting dogs of the Khoikhoi, which were crossed with European dogs by the early colonists of the Cape Colony of southern Africa. De grootte Een volwassen Rhodesian Ridgeback moet een mooie rijzige hond zijn. All affected dogs, even those surgically corrected, should be spayed or neutered and never be bred, since surgical dermoid sinus removal can be extremely cost prohibitive, and because many unremoved dermoid sinuses will eventually abscess. Puppies should always be screened at birth by the breeder and veterinarian, and the examination repeated as the puppies grow before they go to their new homes.

Abscessed dermoid sinuses will be at best a recurrent, painful problem, and if the sinus communicates with the tissues around the spinal cord, cause meningitis and often death. Een beetje wit op de borst en tenen is toegestaan maar overmatig wit op de buik, borst en boven de voeten is niet wenselijk. Dr. Lorna Kennedy at the University of Manchester's Centre for Integrated Genomic Medical Research in England has found the haplotype (group of genes), which, when present, double the chances of a Ridgeback becoming hypothyroid due to lymphocytic thyroiditis. "Genomic Analyses Reveal the Influence of Geographic Origin, Migration, and Hybridization on Modern Dog Breed Development." By the 1860s, European colonisers had also imported a variety of mainly European dog breeds to this area of Africa, including such dedicated hunting dogs as The original breed standard was drafted in 1922 by F. R. Barnes on founding the first Ridgeback Club at a Bulawayo Kennel Club show, then in Southern Rhodesia (now in Zimbabwe), and based on that of the The appearance standard of the Ridgeback originated in Zimbabwe (Rhodesia) and goes back to the year 1922, and by 2019 this standard had remained virtually unchanged.Male ridgebacks usually stand 25–27 in (64–69 cm) at the White is acceptable on the chest and toes.
