OBJECTIVE To investigate whether the presence of neurological signs and magnetic resonance imaging findings could predict the presence of a traction‐responsive lesion in Dobermanns affected by disc‐associated cervical spondylomyelopathy. METHODS Retrospective review of neurological signs and low‐field pre‐ and post‐traction magnetic resonance imaging abnormalities of the cervical spine (abnormal vertebral body shape and vertebral tipping, intervertebral disc degeneration, protrusion and ligamentum flavum hypertrophy) in Dobermanns with disc‐associated cervical spondylomyelopathy. The main outcome of interest was response to linear traction (dynamic versus static) at C6‐C7 intervertebral disc space. The association between investigated variables and response to linear traction was assessed. RESULTS The study included 25 dogs. No association was identified between neurological status grading and the presence of a static or traction‐responsive lesion. Of the investigated magnetic resonance findings, C7‐T1 intervertebral disc degeneration was significantly (P = 0 · 03) associated with the presence of a traction‐responsive lesion at C6‐C7 intervertebral disc space. CLINICAL SIGNIFICANCE The presence of C7‐T1 intervertebral disc degeneration might help in predicting the presence of traction‐responsive C6‐C7 intervertebral disc lesions.
