Hip dysplasia and CCLD are 2 of the most common orthopedic problems in dogs,1 and treatment of these conditions can be associated with substantial financial costs for dog owners.2 Importantly, dogs affected by one of these conditions can be concurrently or subsequently affected by the other. Thus, information about factors associated with whether dogs would develop HD, CCLD, or both could help veterinarians optimize their diagnostic approach and educate their dog-owning clients.
Several previous studies have reported prevalences of these conditions and risk factors for their occurrence on the basis of data from the VMDB,1,3,4 databases maintained by the Orthopedic Foundation for Animals and PennHIP,5–8 and medical records of private veterinary practices9 and veterinary medical teaching hospitals.10–13 All of these previous studies, however, examined prevalence of and risk factors for HD or CCLD individually, and to our knowledge, there have been no studies of prevalence of or risk factors for HD and CCLD occurring together. In addition, these previous studies did not examine temporal changes in the prevalence of HD or CCLD.
Therefore, the purposes of the study reported here were to evaluate prevalences of HD and CCLD, alone and together, in dogs; to determine whether sex, age, and breed were risk factors for the occurrence of HD, CCLD, or both; and to determine changes in prevalences of HD and CCLD over time. We hypothesized that HD and CCLD were more common in large- and giant-breed dogs and that prevalences of HD and CCLD had increased significantly over time due to increased recognition of both HD and CCLD.
