OBJECTIVE: To describe the prevalence, age at first radiographic detection, severity, and progression of thoracic spondylosis deformans (SD) in search-and-rescue (SAR) dogs enrolled in a long-term medical surveillance program.
METHODS: This retrospective case series analyzed thoracic radiographs from 127 SAR dogs. All dogs participated in a 15-year medical surveillance program beginning in 2001. Thoracic radiographs and health data were submitted annually by handlers when available; however, radiographs were not submitted each year consistently, and some data points were missing. One board-certified radiologist reviewed the radiographs for the presence, severity, and progression of thoracic SD. Descriptive statistics were used to summarize signalment and radiographic findings.
RESULTS: Of the 127 dogs evaluated, 81 (63.8%) had thoracic SD identified on radiographs. The average age at first detection was 8.7 years (range, 2.0 to 15.8 years). Severity was classified as mild in 52.9% of cases, moderate in 32.8%, and severe in 14.2%. Radiographic progression occurred in 40% of affected dogs. The condition was observed across multiple breeds, including German Shepherd Dogs and Labrador Retrievers.
CONCLUSIONS: Thoracic SD, an enthesopathy, is a common and sometimes progressive finding in SAR dogs.
CLINICAL RELEVANCE: Although historically considered an incidental finding, the identification of thoracic SD may inform long-term musculoskeletal monitoring and clinical management strategies for SAR and other working dogs.
