A retrospective study on findings of canine hip dysplasia screening in Kenya

Abstract

Aim:The current study was undertaken to evaluate the findings of canine hip dysplasia screening in Kenya.Materials and Methods:Records for 591 dogs were included in this study. The data was obtained from the national screening office, Kenya Veterinary Board, for the period between the years 1998 and 2014. Monthly screening records were assessed and information relating to year of evaluation, breed, sex, age, and hip score captured. Descriptive statistics of hip scores was computed based on year, sex, age, and breed.Results:A total of 591 records from the year 1998 to 2014 were retrieved at the National Screening Centre, the Kenya Veterinary Board. Each record was examined and data pertaining to year of screening, the breed, sex, age of the dogs, and the total hip score were recorded. The highest number of dogs screened for hip dysplasia (HD) was in the year 2009 and the lowest in the year 1998. More females than males were screened for HD and the mean age of all the dogs was 22.9±12.7 months. The most common breeds of dogs screened during the study period were German Shepherd (67.0%), Rottweiler (15.6%), and Labrador Retriever (12.2%). The mean hip score for the 591 dogs was 15.1±10.9 and the median 12.0. The mean hip scores per breed were; German Shepherd (16.3±12.1); Golden Retriever (16.0); Hungarian Vizla (15.0); Labrador Retriever (3.0±6.7); Great Dane (13.3±3.2); Rottweiler (12.2±8.2); Doberman (10.3±4.2); Rhodesian Ridgeback (9.6±3.8); and Boxer (9.3±0.6). Based on the hip score, moderate to severe HD was diagnosed in 16.6% of the dogs, mild HD in 32.7%, Borderline HD in 37.7%, fair HD in 6.9%, and good HD in 6.1%.Conclusion:Canine HD is a common occurrence in Kenya with most dogs suffering mild to border line HD. In addition, German Shepherd and Golden Retriever appear to be the most affected breeds. It is therefore recommended that stringent measures be imposed to dog breeding programs to avoid transmission of this undesirable trait and consequently improve the welfare and the quality of dog breeds in Kenya.

Selection of Breeding Stock among Australian Purebred Dog Breeders, with Particular Emphasis on the Dam

“…Of these important diseases listed by the ANKC, all of the Great Dane breeders tested for hip dysplasia. However, even though hip dysplasia is a common problem in Labrador Retrievers and German Shepherds [48], only around half of breeders reported using Hip Scores on their breeding dogs. This may have been due to not all breeders completing this section of the survey, as registered breeders of Labrador Retrievers must have their breeding dogs hip scored, although this is not mandatory for German Shepherd breeders in Australia [49,50].…”

Modified FCI (Fédération Cynologique Internationale) Scoring of the Coxofemoral Joint in Labrador Retrievers Without and With Hip Dysplasia

“…Canine hip dysplasia (CHD) is a developmental, heritable and multifactorial disorder of the coxofemoral joint with associated joint laxity and incongruity that predisposes to osteoarthritis (1)(2)(3). It affects mainly rapidly growing large breed dogs (4), such as German Shepherds, Labrador Retrievers, and Boxers (5,6). Extended-leg ventrodorsal (VD) pelvic radiograph, first introduced in the 1960s by Riser (7), remains the most commonly used technique for evaluating canine coxofemoral joint according to the FCI (Fédération Cynologique Internationale), OFA (Orthopedic Foundation for Animals), and BVA/KC (British Veterinary Association and the Kennel Club) (8).…”

Abordagem metodológica e temporal sobre estudos da Displasia Coxofemoral em cães de pequeno e médio porte

“…O Boxer e o Beagle também demonstraram relevância nesse contexto, com 5 estudos cada. Essas raças, populares em muitas partes do mundo, parecem ser alvo de estudo frequente, o que pode estar relacionado à necessidade de compreender e abordar questões de saúde específicas a essas populações caninas (Nouh et al, 2014;Kimeli et al, 2015;Clark, 2014).…”
