Agility requires the handler to
direct their dog through a course of various obstacles, scored
for
both time and accuracy. Dogs run off-leash and the handler can only
give voice and body signals. Agility course obstacles include
tunnels, jumps, weave poles, dogwalk and A-Frame. UKC specific
obstacles include the sway bridge, swing plank, and several different
types of jumps not seen on the agility courses of other registries.
