XIX. Official agility size divisions. Entries are separated into three size divisions based on the height at the withers of each individual dog.

A. Determining a dog’s height. A dog’s height is determined by drawing a straight line from the top of the withers perpendicular to the ground while the dog is standing normally and not leaning. Each exhibitor is required to include the height of his/her dog when entering a dog in an agility event.


1. Borderline dogs. If a dog is on the borderline, before the trial the handler should ask the Judge for a measurement so that the dog may be exhibited in the proper division without penalty.

2. Correcting a size division before the dog runs. When a dog is found to be above or below the limit for the size division in which it is entered, the dog must be moved to the proper division.

3. When a dog runs in the wrong size division. When a dog has run the course in the incorrect size division, it must be assessed a non-qualifying score and must not be allowed to re-run in the correct size division. The Judge must mark the reason for the NQ in the Judge’s book. The Judge’s determination of the dog’s height is final.

B. Judge’s option to measure dogs. A Judge may require that any dog be measured. The Judge’s determination of the dog’s height is final.

C. Determining jump height division and crawl tunnel height.
