In agility, three obstacles stand apart from the rest: the A-frame, the dog walk, and the seesaw. They're called “contact obstacles” because each one has painted contact zones that the dog must touch. Getting these right is a big part of what separates clean runs from faulted ones.
What Are Contact Zones?
Every contact obstacle has yellow-painted areas at the bottom of the ascending and descending ramps. These zones are typically about 36 to 42 inches long, depending on the organization and obstacle.
The rule is simple: your dog must place at least one paw in the yellow zone on the way down (the descending contact). Some organizations also require the dog to hit the ascending contact, but the down contact is always judged. If the dog leaps off the obstacle and misses the yellow zone, it's a fault.
Why does this rule exist? Safety. Without contact zone requirements, dogs would launch themselves off the top of the A-frame or fly off the dog walk at full height. The contact zones force dogs to run all the way to the bottom before exiting, which is much safer for their joints and body.
The A-Frame
The A-frame is the most visually dramatic obstacle on course. Two large ramps lean against each other forming an inverted V shape. The dog runs up one side and down the other.
Dimensions and Heights
The A-frame height varies by organization:
- UKI: 5 feet 6 inches at the apex
- AKC: 5 feet 6 inches (Preferred height is 5 feet 1 inch)
- AAC: 5 feet 6 inches for Regular, lower options for Specials and Veterans
Each ramp is about 3 feet wide and 9 feet long. The surface is covered with rubber or a textured coating and has horizontal slats to give dogs traction as they climb.
Common Faults
- Missing the down contact: The dog leaps off before reaching the yellow zone. This is the most common A-frame fault.
- Bailing off the side: The dog jumps off the ramp sideways instead of running all the way down. Usually a training or confidence issue.
- Refusal: The dog stops or turns away before getting on the A-frame.
Training Tips
Most trainers teach either a “running contact” (the dog maintains speed through the zone) or a “stopped contact” (the dog pauses in a two-on-two-off position at the bottom). Running contacts are faster but harder to train reliably. Stopped contacts are slower but more consistent.
The Dog Walk
The dog walk is essentially a balance beam with ramps on each end. The dog walks up one ramp, across a narrow elevated plank, and down the other ramp.
Dimensions
The center plank sits about 4 feet off the ground. Each section (up ramp, center plank, down ramp) is roughly 12 feet long and about 12 inches wide. The total length is around 36 feet from start to finish.
That narrow width is what makes the dog walk challenging. On the A-frame, the ramps are 3 feet wide — plenty of room. On the dog walk, the plank is only about 1 foot wide, and it's 4 feet in the air. Dogs need good balance and confidence.
Common Faults
- Missing the down contact: Same as the A-frame — the dog jumps off too early.
- Falling or jumping off: Especially with dogs that are nervous about the height or narrow plank.
- Creeping: Not a fault per se, but a very slow, cautious dog walk indicates a confidence issue that should be addressed in training.
Training Tips
Start with the plank on the ground so the dog learns to walk on a narrow surface without worrying about height. Gradually raise the height as the dog gains confidence. Many training facilities have adjustable dog walks for this purpose.
The Seesaw (Teeter-Totter)
The seesaw is a single plank balanced on a central pivot point. One end starts on the ground and the other is elevated. As the dog walks past the center point, the plank tips, and the raised end comes down to the ground.
Dimensions
The seesaw plank is typically 12 feet long and about 12 inches wide. The pivot point is usually around 24 inches high at the center. When one end is on the ground, the other end is roughly 4 feet in the air.
Why the Seesaw Is the Hardest Contact
The seesaw moves. That simple fact makes it fundamentally different from the A-frame and dog walk, which are solid and stable. The dog has to:
- Walk up an incline that changes angle mid-way
- Shift their weight past the tipping point
- Ride the plank down as it drops
- Wait for the end to touch the ground
- Hit the contact zone before stepping off
The sound of the plank hitting the ground can also startle dogs, especially in loud, echoing indoor venues. Building positive associations with the seesaw early in training is critical.
Common Faults
- Fly-off: The dog jumps off before the end touches the ground. This is both a fault and a safety concern.
- Missing the contact: The dog exits without touching the yellow zone.
- Refusal: The dog won't get on the seesaw, or stops and backs off after feeling it start to tip.
Training Tips
Use a low, stable practice seesaw at first. Let the dog get comfortable with the motion before adding height. Reward the dog heavily for riding the plank down to the ground. Some trainers use a “bang game” — teaching the dog to drive the end of the board down enthusiastically rather than cautiously.
How Organizations Differ
While the basic concept of contacts is universal, organizations differ in some details:
- Contact zone length: Can vary by a few inches between organizations
- A-frame height: Most use 5 feet 6 inches, but some offer lower heights for smaller dogs or veterans programs
- Judging strictness: Some judges are known for calling contacts more tightly than others, though all follow their organization's rules
- Running vs. stopped contacts: All organizations allow both approaches — it's a training choice, not a rule difference
If you compete in multiple organizations, the equipment will feel familiar. The key differences are usually in jump heights and course design, not in how the contacts themselves work.
Barkloop tracks every contact fault, every clean run, and every placement across all your classes. Whether your dog nails the A-frame or needs a little more practice on the seesaw, your results are always recorded accurately.
