“…The BVA (British Veterinary Association)/KC hip dysplasia (HD) and elbow dysplasia (ED) schemes hold data on over 100,000 radiographs assessed since 1984. Dogs evaluated under these schemes must be permanently identified by microchip or tattoo [ 166 ] and breed median scores are published to assist breeding decisions [ 167 ]. Linkage between HD and ED schemes results and KC pedigree data has allowed pedigree evaluation and generation of estimated breeding values (EBVs) [ 168 ] for HD [ 169 ] and ED [ 170 ] in Labrador Retrievers.…”

“…Canine health schemes generally harvest primary data from voluntary owner submissions and often benefit from well-characterised data, permanent animal identification (microchip, tattoo), openly published results and linkage with genetic databases [ 166 ]. However, intrinsic selection bias from passive collection processes and questionable representation of the overall dog population limit the generalisability of study results.…”

Effective canine health surveillance systems can be used to monitor disease in the general population, prioritise disorders for strategic control and focus clinical research, and to evaluate the success of these measures. The key attributes for optimal data collection systems that support canine disease surveillance are representativeness of the general population, validity of disorder data and sustainability. Limitations in these areas present as selection bias, misclassification bias and discontinuation of the system respectively. Canine health data sources are reviewed to identify their strengths and weaknesses for supporting effective canine health surveillance. Insurance data benefit from large and well-defined denominator populations but are limited by selection bias relating to the clinical events claimed and animals covered. Veterinary referral clinical data offer good reliability for diagnoses but are limited by referral bias for the disorders and animals included. Primary-care practice data have the advantage of excellent representation of the general dog population and recording at the point of care by veterinary professionals but may encounter misclassification problems and technical difficulties related to management and analysis of large datasets. Questionnaire surveys offer speed and low cost but may suffer from low response rates, poor data validation, recall bias and ill-defined denominator population information. Canine health scheme data benefit from well-characterised disorder and animal data but reflect selection bias during the voluntary submissions process. Formal UK passive surveillance systems are limited by chronic under-reporting and selection bias. It is concluded that active collection systems using secondary health data provide the optimal resource for canine health surveillance.

“…Canine radiographic screening schemes are currently well established and commonly used for hip and elbow dysplasia. 12 More recently, a Chiari malformation/ syringomyelia scheme using MRI has been implemented. 13 Although no oicial screening scheme for CVM exists, several breeding associations (French Bulldogs and Pugs) have already implemented diferent radiographic screening protocols based on a single lateral view, or in combination with ventrodorsal/dorsoventral views.…”

Evaluation of radiography as a screening method for detection and characterisation of congenital vertebral malformations in dogs

et al. 2018

Congenital vertebral malformations (CVM) are common in brachycephalic 'screw-tailed' dogs; they can be associated with neurological deficits and a genetic predisposition has been suggested. The purpose of this study was to evaluate radiography as a screening method for congenital thoracic vertebral malformations in brachycephalic 'screw-tailed' dogs by comparing it with CT. Forty-nine dogs that had both radiographic and CT evaluations of the thoracic vertebral column were included. Three observers retrospectively reviewed the images independently to detect CVMs. When identified, they were classified according to a previously published radiographic classification scheme. A CT consensus was then reached. All observers identified significantly more affected vertebrae when evaluating orthogonal radiographic views compared with lateral views alone; and more affected vertebrae with the CT consensus compared with orthogonal radiographic views. Given the high number of CVMs per dog, the number of dogs classified as being CVM free was not significantly different between CT and radiography. Significantly more midline closure defects were also identified with CT compared with radiography. Malformations classified as symmetrical or ventral hypoplasias on radiography were frequently classified as ventral and medial aplasias on CT images. Our results support that CT is better than radiography for the classification of CVMs and this will be important when further evidence of which are the most clinically relevant CVMs is identified. These findings are of particular importance for designing screening schemes of CVMs that could help selective breeding programmes based on phenotype and future studies.
