Schipperke Movement
Proper Schipperke movement is a smooth, well coordinated and graceful trot (basically double tracking at a moderate speed), with a tendency to gradually converge toward the center of balance beneath the dog as speed increases. Front and rear must be in perfect balance with good reach in front and drive in the rear.
(From the AKC STANDARD)
Proper Side Gait Showing Good Reach And Drive

NOTE THE NICE EXTENSION FRONT AND REAR
NOTE THE TOPLINE REMAINS LEVEL AND DOESN'T SAG OR BREAK
NOTE THE POSITION OF THE OTHER 2 PAWS
NOTE THAT THE DOGS FEET BARELY CLEAR THE GROUND
Side Gait
From the Illustrated Guide to the Standard
Lacking Reach And Drive

NOTE THE POSITION OF THE TWO "EXTENDED LEGS"...THIS DOGS LACKS BOTH REACH AND DRIVE.
IF THE DOG HAD GOOD REACH, THE EXTENDED FRONT LEG WOULD REACH TO THE END OF THE DOG'S NOSE...THE REAR LEG WOULD EXTEND BEHIND THE DOG.
NOTE THE AMOUNT OF SPACE BETWEEN THE OTHER 2 PAWS
WHILE THIS DOG MIGHT MOVE "BALANCED" AT BOTH ENDS, HE WOULD NEVER BE ABLE TO DO THE JOB HE WAS BRED TO DO...DUE TO THE LACK OF REACH AND DRIVE, HE WOULD TIRE EASILY.
Schipperke Gait Coming
NOTE THAT ALL LEGS ARE MOVING IN THE SAME DIRECTION
IDEAL GAIT COMING OR GOING...ALL LEGS AND FEET SHOULD BE TRACKING IN THE SAME DIRECTION
THIS IS A BEAUTIFUL EXAMPLE OF DOUBLE TRACKING
NOTE THE EQUAL DISTANCE BETWEEN THE FRONT AND REAR LEGS AND FEET
NOTE THERE IS NO SWINGING OF THE LEGS
NOTE THAT THE DOGS FEET BARELY CLEAR THE GROUND
Schipperke Gait Going
Note that when the dog is coming or going you only see one set of legs.
This is considered "clean" gait and while hard to achieve, is desirable.
Moving correctly in front and too narrow behind

While this type of movement is often seen in the ring, it is not correct.
For a time, this type of movement was seen so often and was so prevalent that it was considered by many people to be correct for the schipperke.
When the schipperke moves correctly, all four legs reach forward and extend rearward at equal distances. The front paw flexes (thus the need for a slight bend to the pastern) on the follow through under the body and the hind foot slips neatly under it to occupy the spot vacated by the front foot.
For the schipperke to move with good reach and drive, it is necessary for the front to sit well underneath the body as described by the standard.
