Rhodesian Ridgeback
Temperament
Rhodesian Ridgebacks are known to be loyal and intelligent. They are typically somewhat aloof to strangers, but this is not to be confused with aggression; a Rhodesian Ridgeback with a good temperament will not attack a stranger without a reason. Because they require consistent training and correct socialization, they are often not the best choice for inexperienced dog owners or families with young children.
Genetics of the ridge
The genetic test which distinguishes dominant homozygotes (R/R - two ridge genes) from heterozygotes (R/r - one ridge gene) is available (www.genocan.eu/en). Using the genetic test, a breeder may accurately predict birth of ridgeless puppies.
Resources
RRCUS H&G - the Rhodesian Ridgeback Club of the United States maintains a web site devoted to the breed's health issues that also gathers ongoing research for their Health & Genetics Committee. This group recommends that breeders perform at least four health screenings: hips, elbows, thyroid and eyes, with cardiac and hearing tests optional.
