Tracking Dog Excellent judges must plot cross-tracks at two widely separated places, never on the same leg or on the first leg. Well designed cross-tracks take careful planning, and judges should consider the cross-track entry, crossings and exit before they start plotting a TDX track. One useful design is to plan cross-tracks on parallel legs of the track. This configuration condenses the space taken up by the cross-tracks by using (minimally) 50 yards (after the first crossing and before the second crossing) for both tracks on the same part of the field.
A dog that follows the cross-track for more than 50 yards will be failed. In the example above, a dog taking the cross-track on leg 3 and then joining the primary track on leg 5 should be failed for taking the cross-track.
Happy Tracking!
