The number of metacarpals varies widely among species, as the demand for their function changes: plantigrade, or flat-footed, animals requiring the full complement of five metacarpal bones; the number is reduced in the upright stature of digitigrade animals such as the dog and cat, and shows the extreme in unguligrades like the horse, which depends entirely on the third metacarpal bone for its stature.

Metacarpal bones There was one metacarpal bone in BBG but five in d og for each forelimb (Figure 13). The metacarpal joint is defined by the presence of palmar sesamoids, which allow the flexor tendons to pass over the sharp change in angle presented by the joint. 55.

The forelimb skeleton consists of the thoracic or pectoral girdle and bones of the forelimb (see Figures 5-5 and 5-6). The size of forelimb bones varies a great deal, because of the greater variation in size for breeds of dogs. The forelimbs bear 60% of the dogs weight.
