The jaunty gait!
This dog wastes motion both front and rear. His movement is not balanced and he bounces as he moves.
Front reach- at first look I would say this dog lacks reach because the front feet fall somewhere below the neck but he initially reaches well forward under the muzzle, the problem here is not reach but rear drive. He also lifts his front feet too high when extended.
Front drive/rear reach-front drive could be better rear reach looks good but falls short of front feet due to lack of front drive.
Rear drive- too much up & down movement of the legs here. Hocks are not fully extended, does not drive himself forward with his rear.
