Safe Obstacle Performance: What a Criterion Is and How to Teach It

Every agility obstacle has a safe way to be performed, and a set of smaller behaviors a dog learns before it meets the full-size version. Coaches call the target behavior a performance criterion. This lesson explains what criteria are, why they matter for a dog's body as much as for its score, and how a coach teaches them in steps.

By the end you should be able to describe, for each type of obstacle, what "done well" looks like and why, and how to split it into parts a young dog can learn.

What a performance criterion is

A criterion is a precise description of how the dog should perform an obstacle: where it takes off, where its feet go, what it does at the end. "Go over the jump" is not a criterion. "Take off at a comfortable distance, jump in a smooth arc, and land looking toward the next obstacle the handler indicates" is closer.

Clear criteria matter for three reasons:

• Safety. Awkward performance repeated many times (jumping flat and landing hard, crashing into the weave poles, leaping off a contact from height) puts avoidable strain on a dog's body. A defined, efficient way of performing each obstacle reduces it.
• Consistency. A dog that knows exactly what is expected performs the same way at a club night and at a noisy trial.
• Communication. If the handler and coach agree on the criterion, they can tell whether a mistake came from the dog, the handler's cue or the setup.

Teams often choose between valid options (for example, stopped or running contacts). The coach's job is to help them choose one, define it precisely, and teach it consistently.

The obstacles and what to look for

Jumps. The dog should take off and land in balance, with a rounded back, and turn efficiently afterward. Bars must be displaceable, so they fall if the dog touches them rather than tripping it. Jump heights are set by each organization's rules, usually by the dog's size; check the current rules for the organization your students compete in. Before full-height jumping, dogs learn body awareness, collection and extension on the flat and over very low bars.

Tunnels. The dog should drive straight in and out without hesitation. A tunnel that rolls or shifts when a dog hits it at speed is a hazard, so it is always secured. Tunnels are often among the first obstacles introduced because they need no height.

Weave poles. The dog enters with the first pole at its left shoulder and moves through the line without skipping poles. Entries from different angles, and staying in while the handler moves away, are the hard parts. Methods vary (channel weaves, guide wires, two-by-two), and most start with a small number of poles and build up.

Contact obstacles. The A-frame, dog walk and seesaw have painted zones at each end, and the dog must touch the zone as it comes down (in competition, rules fault a dog that misses it). The criterion defines how the dog behaves in that zone: a stopped position such as two back feet on the board and two front feet on the ground, or a trained running contact. Either way, the goal is a controlled descent, not a leap from height.

The seesaw. The board moves under the dog. A dog needs to learn to ride it down calmly and wait for it to hit the ground. This is taught with a board that barely moves, very close to the ground, before height and movement are added. A dog frightened by a board that bangs down can take a long time to regain confidence.

How criteria are taught

Coaches teach criteria in the same way good trainers teach any behavior: in small steps, one change at a time.

1. Split the behavior. Teach the end position of a contact on a plank on the ground, or the weave entry with two poles, before the full obstacle.
2. Reward in position. Deliver the reward where you want the dog to be (in the contact zone, at the exit of the weaves) so the dog learns where the valuable place is.
3. Raise one thing at a time. Height, speed, angle of approach, handler position and distractions are each a separate step. If you add two at once and the behavior breaks, you will not know which one caused it.
4. Add the handler's motion late. Many criteria hold when the handler stands still and fall apart when they run. That is expected; it needs its own practice.
5. Keep it short. Short, successful repetitions build a clear picture without tiring the dog.

A dog's physical maturity sets the pace for height and impact. When a young dog is ready for full-height jumps or contacts depends on the individual, and its vet is the right person to advise. Our article on starting puppies in agility safely covers what young dogs can learn at ground level, and agility equipment safety and course design looks at the equipment itself.
