MR images provide for the exact assessment of the brain, including ventricular size. Still inter‐ and intrabreed comparison of ventricle size is difficult due to the varying anatomies in dogs. To compare the ventricle area of different sized breeds, 25 dogs (13 Yorkshire Terriers and 12 German Shepard dogs) were reviewed, retrospectively. Hemisphere and ventricle of each side were outlined manually three times. All measurements were averaged and their percentage (ventricle area by hemisphere area) was defined as the relative ventricle area. This value in Yorkshire Terriers (5.3) was significantly higher compared to German Shepard dogs (1.7). However, on the basis of the neurologically symptomatic sample (7 Yorkshire Terriers) in this study, threshold values of normal and abnormal relative ventricle areas could not be detected.
