my own experience with analyzing mri scans of dog brains have not been fruitful from the brain morphometry perspective. the reason is that the scan parameters of the brains i worked with were not setup for morphometry (rather, for clinical diagnostics) and so were lacking in major areas, namely the contrast was not setup to discriminate gray matter from white matter (mainly they were T2-like) and the resolution was typically 2.5 to 4.5mm in one plane, which makes it hopeless to reconstruct surfaces or resolve subcortical structures.
but my approach was attempting to use freesurfer tools. it is possible to conduct a morphometry analysis by manually segmenting slices, but this would of course be very time consuming. so if you could get images that are T1-weighted, optimized for gm/wm contrast, and close to 1x1x1mm resolution, then the freesurfer tools could be used. manual work would still be required (akin to work on primate brains). there are others i know who have tried, so i can put you into contact with them if you want. n.
