Prevalence of canine hip dysplasia in 10 breeds in France, a retrospective study of the 1997-2017 radiographic screening period

Abstract

Canine hip dysplasia (HD) is a complex developmental disease of the coxo-femoral joint and is one of the most common orthopedic conditions in dogs. Due to the genetic contribution, most of the programs fighting against HD recommend selective breeding that excludes affected dogs. Using the best-scoring dogs for breeding may reduce the prevalence of HD. In France, the phenotypic screening of coxo-femoral joint conformation remains a strategy for breeders to establish selection decisions. The HD prevalence was evaluated in 10 breeds, based on the assessment of 27,710 dogs, during the 1997-2017 screening period, which was divided into 3 homogeneous cohorts for analysis. The global HD prevalence varied widely among breeds from 5% (Siberian Husky) to 51.9% (Cane Corso). It decreased over time in 6 breeds, among which 4 (Cane Corso, Gordon Setter, Rottweiler and White Swiss Shepherd) showed a significant decrease. A statistically significant increase in HD prevalence was noted for the Siberian Husky. Although the efficacy of phenotype-based breeding programs remains controversial, our results are in accordance with several recent studies showing that longterm selection policies are valuable, as they may help decreasing the HD prevalence in some breeds. The complementary use of more recent tools such as estimated breeding values and genomics would probably help breeders achieve more substantive results.

“…These results are consistent with previous studies indicating that selective breeding using classifications of hip joint phenotypes might improve hip conformation in several breeds of dogs [5,7,[10][11][12][13][14][15][16], although other studies showed different findings, and the efficiency of using screening programs to reduce the prevalence of HD has been questioned [17][18][19][20].…”

“…The aim of our observational study was to compare the HD prevalence in affected breeds over several periods of time to evaluate the effectiveness of the hip dysplasia control program in France. This study is complementary of a first one [16], which was recently published and related to 10 other breeds, over the 1997-2017 screening period.…”

“…While several reports identified a decrease in HD prevalence [5,7,[10][11][12][13][14][15][16], others failed to identify any significant progress [17][18][19][20].…”

“…É uma patologia que se manifesta com mais frequência em animais de médio e grande portes, possui importante influência genética e impacta negativamente na saúde e bem-estar, pois os animais começam a ter dificuldade para realizar atividades básicas como caminhar, subir em degraus, levantar, entre outras (BALDINGER et al, 2020;JAMES;MCDOWELL;LEWIS, 2020). A idade é um fator de grande relevância, pois com as alterações fisiológicas decorrentes do envelhecimento , alguns mecanismos de proteção da articulação não são mais tão eficientes e aceleram o processo de degeneração das articulações (FERRARI et al, 2018).…”

“…Canine hip dysplasia (CHD) is one of the most common orthopedic diseases in young dogs without a traumatic background, especially in large and predisposed breeds. This condition leads to significant orthopedic effects and pain in aging animals through the development of osteoarthritis (OA) ( 1 , 2 ).…”
