About the Dog's Jumping Arc
By Linda Mecklenburg

The jumping arc is the dog's trajectory over the bar as viewed
from the side at ground level. It is important to recognize
the jumping arc is just that: an arc. See Figure 1. The takeoff
and landing points, and the height of the bar, determine the
amount of curvature in that arc; that is, how round or flat the
jumping arc is.

When the dog jumps with true collection, he will jump with
a round jumping arc. A round jumping arc has a takeoff
and landing distance roughly equal to the height of the bar,
and the dog's jumping effort is mostly vertical. A round
jumping arc is desirable when a tight turn follows the jump.
See Figure 2.
When the dog jumps with relative collection or extension,
he will jump with a flat jumping arc. A flat jumping arc has
a takeoff and landing distance greater than the height of the
bar, and the dog's jumping effort is mostly horizontal. A flat
jumping arc is most desirable for straight lines.

Although your dog's physical structure may limit the extent to
which he can vary his jumping arc, even a dog that is naturally
athletic and agile must be taught how and when to change his
jumping arc. Once you teach your dog that he can change his
jumping arc, you should strive to cue him to do so when desired.
The peak of a dog's jumping arc should be high enough to clear the
bar. Jumping too high or too low is not desirable. Jumping higher
than necessary is not efficient and it is more taxing physically. It
is normal for novice dogs to overjump, but this usually goes away
with experience. Some dogs have problems with their jumping
technique, such as inefficient folding of their front or rear legs,
which will cause them to jump higher than needed. If your dog is
jumping too high, it is important to identify the cause to decide
if intervention is necessary. See Figure 3. Jumping lower than
necessary is obviously a problem that results in knocked bars.
Often handlers blame knocked bars on flat jumping arcs, but
the cause is the height of the arc, not how round or flat it is. See
Figure 4.
