Malformations of the canine manus are infrequently cited in the litera
ture but include polydactylia and syndactylia. Here, a case of brachym
etacarpalia affecting the second and fifth metacarpal bones of both fo
relimbs of a mixed-breed dog is described. The initial impression of s
hortened digits was disproved by statistical comparison with normal sk
eletons, but the presence of shortened metacarpal bones was demonstrat
ed. Other malformations of the manus and appropriate terminology are b
riefly discussed.
