The Rhodesian Ridgeback World Congress

Health Committee

Created in 2012 with the mandate to be a clearinghouse for health information for Ridgeback clubs worldwide, and to help generate cooperation in coordinating research and information exchange across the globe.


2016 RR Congress Issues Resolution

The 2016 Rhodesian Ridgeback World Congress convened June 29-30 in Lund, Sweden, for two days to discuss issues of interest to Ridgeback owners, breeders, and fanciers. Attendees at the close of the Congress approved the following resolution:


"The 2016 Rhodesian Ridgeback World Congress recognizes that breeders are autonomous and are the best arbiters of what should happen in their whelping boxes. To that end, the 2016 RRWC strongly encourages breed clubs to avoid punitive language in their codes of ethics or other official documents regarding the breeding of healthy Rhodesian Ridgebacks with only cosmetic faults, and strongly encourages openness and honesty between breeders."

Ridgeback Deafness Update

EOAD, or early onset adult deafness, is a genetically transmitted form of heritable deafness that affects Ridgebacks between two months and two years of age. If you would like your dog to be tested for EOAD, visit the Discovery Testing page at projectdog.org. The code required at the bottom of the page is liondog. Please be aware that because testing is conducted in batches of 100, immediate results may not be available.

Juvenile epilepsy study underway in Finland

Researchers in Finland have discovered a novel gene for juvenile myoclonic epilepsy in the Rhodesian Ridgeback. Characterized by strong muscle jerks or twitches, this form of epilepsy typically surfaces from 6 weeks to 18 months of age.

Degenerative Myelopathy modifier found

Degenerative myelopathy is a painless but devastating neurological condition that leads to a slow but irreversible paralysis of the rear legs. Many breeds are affected by DM, including Ridgebacks. A genetic-marker test is available that  identifies dogs who carry a gene called SOD1 that increases the risk of  DM, but not all dogs with two copies of the SOD1 gene develop the disease. Researchers from the Broad Institute at MIT and Harvard University recently announced that Pembroke Welsh Corgis that carried a second gene, called SP110, were likely to develop DM at an earlier age. Unfortunately, there is not yet enough data on other breeds, including Ridgebacks, to determine if the presence of the SP110 gene is significant in terms of the expression of degenerative myelopathy. Stay tuned.

Calling all researchers!

The Health Committee of the Rhodesian Ridgeback World Congress is interested in speaking to researchers about organizing a study on the effect of folic acid on dermoid sinus, a neural tube abnormality affecting a small percentage of Ridgeback puppies. An earlier study presented at at the 1996 RR World Congress that was never formally published found that supplementation with folic acid, which is found in many foods, including leafy green vegetables, markedly reduces and even eliminates the expression of this congenital disorder. Researchers can expect a high degree of participation and cooperation by Ridgeback breeders around the world. Contact Denise at revodana@aol.com for more information.
