Rhodesian Ridgeback Health
The Club strongly supports the KC/BVA Hip/Elbow dysplasia schemes and recommends that all Club members ensure all breeding stock is Hip and Elbow scored before they are bred from. The Club also asks Club members that breed or have stud dogs, that they should only breed from KC registered Rhodesian Ridgebacks which conform to the Breed Standard and are believed to be clear from hereditary defects and underlying health conditions, are mentally and physically sound and not suffering from acute nervousness or aggressive tendencies.
The Club has long held the belief that possible health problems should be acknowledged and confronted.
The breed can be affected with a condition called Dermoid Sinus (DS). This is a problem that can be detected at birth. You should be able to buy a puppy without this problem very easily. However some breeders are either ignorant of the problem or do not know how to check for it. Being told a vet has checked the litter is OK provided the vet knows about the condition and how to detect it. In the past the Club has produced a video for use by vets and breeders to help them identify the condition. If left undetected, a sinus becomes a very big problem and causes a lot of pain and suffering. What looks like a lump (which may be found and the whole area must be checked from the top of the head, along the dog’s neck /shoulder area to the base of the tail) is in fact a kind of abscess often reaching into the spinal cord. Needless to say it is excruciating for the dog. However, if detected, many Vets can now confidently and successfully operate to remove the DS and the puppy can go on to lead a happy, normal life. Do make sure that your puppy has been competently and regularly checked for DS. The Club holds a list of competent vets who have successfully operated on Dermoid Sinus affected puppies.
As far back as 1968 the Club funded a research programme at Bristol University into the incidence of Dermoid Sinus. All Club members are made aware of the condition and the importance of checking for it’s presence in newly-born puppies by at least two competent persons. In 1997 the club initiated the Dermoid Sinus Project with the ultimate objective of establishing a DNA test for the condition which could, eventually, lead to it’s elimination from the breed. The club has previously helped fund research in Sweden into Dermoid Sinus. Dr Nicolette Hilbertz of the Swedish University of Agricultural Sciences published a paper back in 2008 with her interim findings, together with our and others funding, had continued her research with amazing and unexpected results – but then due to unexpected genetic findings she experienced herself, this report has been delayed and will take more time until it is published. Hopefully, in the future she will be able to produce a long awaited genetic test for dermoid sinus. This research is cutting edge genetic research and as technology becomes more available so does the likelihood of understanding how and why a small percentage of our breed (and other ridged and non ridged breeds) are susceptible to dermoid sinus.
Although hip dysplasia is not a big problem in ridgebacks, it does occur. Hip dysplasia (HD) means that the hip bones are not fully in the sockets. This can sometimes cause a problem early on or can show up much later in a dog’s life, it is very painful to the dog and eventually they will be unable to walk. Certain families carry a higher incidence of HD than others do. Check that the parents and hopefully the grandparents of your puppy have been scored, and that they have a low score. The average for the breed is 7 for both hips, and the maximum score for any one dog is 106. The hip and elbow score of the parents is now printed on the puppy’s KC registration form; if it is not there the parents have not been scored. Breeders can come out with a variety of excuses about why they have not had their dogs checked, but since it is not expensive when you consider the price of a puppy, and can cause great distress to you the owner, as well as your dog, do not accept these excuses.
The current BVA/KC scoring scheme for hip dysplasia (HD) has been in operation since 1984 and since then over 100,000 X-rays have been assessed. Dysplasia means abnormal development, and the degree of hip dysplasia present is indicated by a score assigned to each hip.
The hip score is the sum of the points awarded for each of nine aspects of the X-rays of both hip joints. The minimum hip score is 0 and the maximum is 106 (53 for each hip). The lower the score the less the degree of hip dysplasia present. An average (or mean) score is calculated for all breeds scored under the scheme and advice for breeders is to use only breeding stock with scores well below the breed mean score.
The minimum age for hip scoring is one year, and each dog is only ever scored once under the scheme.
More and more responsible breeders are also (and have been for a number of years) have included scoring for Elbows in their breeding programmes. The current BVA/KC scoring scheme for elbow dysplasia (ED) was launched in 1998. An elbow grade is a measure of any evidence of elbow dysplasia (abnormal development). Both elbows are graded (between 0-3), but only the higher grade is used as an overall elbow grade for the dog. The lower the grade the better, with the advice given to breeders from the Kennel Club, is to ideally breed from dogs which have an elbow grade of 0.

Being a large breed that grows fast, some puppies can be susceptible to OCD (Osteochondrosis). This is believed to be partly inherited and partly environmental. How you rear your puppy and feed it is very important.
