Intravertebral and intervertebral ratios are used in horses and can predict cervical vertebral malformation. Intervertebral ratios could be a useful screening method for canine cervical spondylomyelopathy. Our purpose was to compare cervical intervertebral and intravertebral ratios in normal vs. affected<jats:bold><jats:styled-content style=\"fixed-case\">D<\/jats:styled-content><\/jats:bold>oberman pinschers. Forty dogs were studied, 27 affected and 13 normal. Cervical radiographs were obtained in all dogs.

Comparisons were made between groups and specific vertebral body and disc levels. The effect of gender, age, and method of measurement (analog or digital radiographs) was also studied. There was no difference in either the intervertebral or intravertebral ratio between normal vs. affected dogs. The ratios decreased progressively along the cervical spine, being smallest at<jats:bold><jats:styled-content style=\"fixed-case\">C<\/jats:styled-content><\/jats:bold><jats:sub>6<\/jats:sub>\u2013<jats:bold><jats:styled-content style=\"fixed-case\">C<\/jats:styled-content><\/jats:bold><jats:sub>7<\/jats:sub>and<jats:bold><jats:styled-content style=\"fixed-case\">C<\/jats:styled-content><\/jats:bold><jats:sub>7<\/jats:sub>, respectively.
