Hypothesis 3

A tumor or degenerative process has affected the nerve supply to the hock extensor 
mechanism. The motor nerves are affected and the motor function of the stifle and 
hip joints are not affected. Neurological function - pain sensation, 
proprioception, motor function are all working except for the motor to the hock 
extensors. The gaps that are palpated are because the muscle is flaccid. The 
lesion is in the ventral roots of the spinal cord at the level(s) at which the 
hock extensor nerves come out of the canal or the cord.
