Vertical force curve in the pads of a dog affected with CCLR. Force curves reflect vertical force analysis of each footpad of a dog affected with CCLR during a valid passage. The same passage was sagitally separated to facilitate visualization and comparison between the affected and the contralateral hindlimb. The typical M-shaped waveform can be seen in the healthy, but not in the affected hindlimb. Peak vertical force is lower in the metatarsal pad of the affected hindlimb.
