Survey radiographic studies of the lumbosacral region of Belgian Malanois dogs with confirmed lumbosacral degenerative stenosis were reviewed. Affected dogs were compared with an age/weight/breed-matched subpopulation of normal dogs. Quantitative parameters of normalized lumbosacral vertebral canal height, neutral lumbosacral angle, flexed lumbosacral angle, extended lumbosacral angle, lumbosacral range of motion, dynamic lumbosacral malalignment and radiographic findings of lumbosacral disc space collapse, lumbosacral spondylosis, and presence of transitional vertebrae were used to construct a logistic regression model to discriminate normal from affected dogs. This breed-specific data was also used to evaluate the previously reported logistic regression model for lumbosacral degenerative stenosis in large breed dogs.
