14.3 The Humane Hierarchy Framework: Levels 1 Through 6

14.3 The Hierarchy of Behavior Change Procedures: Levels 1–6

Quick Answer: CCPDT’s current hierarchy has six levels: (1) Health, Nutritional, and Physical Factors; (2) Antecedents; (3) Positive Reinforcement; (4) Differential Reinforcement of Alternative Behavior; (5) Extinction, Negative Punishment, and Negative Reinforcement; and (6) Positive Punishment. Practitioners assess earlier levels before moving upward, but safety management, teaching, veterinary care, and referral can operate together. The hierarchy never authorizes a practice prohibited by current policy.

How to Use the Hierarchy

The hierarchy structures questions, not just techniques. Begin by asking whether health and welfare are adequate and whether the environment can prevent the problem. Then teach and reinforce useful behavior. More intrusive consequence procedures require stronger justification, competence, monitoring, and documentation.

Do not turn the hierarchy into six calendar phases or claim that every imaginable procedure at one level must literally be exhausted. A dog in immediate danger needs management now. A dog with pain needs veterinary care while risk is controlled. A trainer lacking competence refers rather than climbing. Current tool-specific and categorical prohibitions remain in force at every level.

Level 1: Health, Nutritional, and Physical Factors

Behavior is affected by pain, disease, sensory change, sleep, hydration, nutrition, exercise, elimination needs, medication, and physical environment. Sudden onset, touch sensitivity, movement reluctance, altered appetite, house-soiling, or neurologic signs warrant veterinary involvement.

The trainer observes and documents; the veterinarian diagnoses and treats. Level 1 does not mean prescribing diets or supplements. It also includes species-typical needs, rest, appropriate activity, and an environment that supports welfare.

Level 2: Antecedents

Antecedent arrangement changes what happens before behavior. Examples include distance from a trigger, a gate at the door, opaque window film, a quiet mat, predictable session order, safer equipment, reduced class density, or scheduling when the environment is manageable.

Management prevents rehearsal and injury but may not teach a replacement skill by itself. It can be temporary or lifelong. An antecedent should not be called humane merely because it occurs before behavior; forcing a dog into an inescapable setup can still harm welfare.

Level 3: Positive Reinforcement

Positive reinforcement adds a consequence after behavior and increases that behavior in the future. It supports acquisition of skills such as orientation, stationing, recall, loose-leash walking, and cooperative care. The consequence must function as reinforcement for that individual in that context.

Good mechanics include achievable criteria, clear feedback, appropriate timing and delivery, choice of reinforcer, breaks, and generalization. Food, play, access, distance, sniffing, and social interaction can reinforce behavior depending on preference and function.

Level 4: Differential Reinforcement of Alternative Behavior

DRA reinforces a specified alternative while reducing reinforcement for the target behavior. The alternative should be feasible, safe, and ideally serve the same function. DRI is a form using behavior physically incompatible with the target. DRO reinforces the absence of the target during an interval but can accidentally strengthen unrelated behavior if poorly designed.

Examples include teaching a mat station instead of door rushing, a chin rest instead of struggling during handling, or an appropriate distance-increasing response instead of lunging. Continue antecedent support so the learner can succeed.

Level 5: Extinction, Negative Punishment, and Negative Reinforcement

Extinction withholds the consequence that previously maintained a behavior. It can produce variability, frustration, and temporary escalation; it may be unsafe for aggression and ineffective when the true reinforcer remains available.

Negative punishment removes or postpones an appetitive event after behavior, such as briefly pausing play after teeth contact. It should be brief, predictable, proportionate, and paired with teaching what works.

Negative reinforcement increases behavior through removal or avoidance of an aversive stimulus. Its welfare impact depends on the stimulus, predictability, control, and alternative behavior. It is not synonymous with punishment, but it requires an aversive condition and therefore deserves careful scrutiny. Some implementations or equipment uses are prohibited regardless of level.

Level 6: Positive Punishment

Positive punishment adds a consequence after behavior and decreases that behavior. The scientific definition does not mean “good punishment.” Risks include fear, pain, escape, conditioned negative associations, suppressed warning, and aggression. Effectiveness at reducing a response does not by itself establish ethical acceptability.

CCPDT’s current position allows consideration of limited, otherwise permitted procedures in particular safety contexts only after earlier levels are assessed and with competence, documentation, data, consent, and welfare monitoring. The Prohibited Practices Policy excludes many acts and certain uses outright. A trainer should not use Level 6 because a client is impatient, food delivery was inconvenient, or the trainer lacks skill at lower levels.

Parallel Responsibilities

Across all levels:

• define the target and replacement behavior;
• protect immediate safety;
• respect dog and client needs and accommodations;
• obtain informed consent;
• check scope and competence;
• measure function, outcome, and welfare;
• generalize and maintain useful behavior;
• document material decisions; and
• consult or refer when needed.

A plan can use Levels 1 through 4 together: veterinary pain treatment, window film, reinforcement of orientation, and DRA for a mat response. The hierarchy guides the selection and review of procedures; it does not forbid integrated care.

Scenario Example

A dog suddenly growls during hip grooming. Level 1 calls for stopping painful-looking handling and veterinary evaluation. Level 2 uses a barrier and avoids the trigger while the dog is assessed. When cleared, Levels 3 and 4 can build voluntary stationing and a chin-rest start behavior. Continuing to brush through the growl under extinction or adding a correction would skip the medical concern, increase bite risk, and suppress communication.

The best examination answer often identifies that sequence and the professional boundary, rather than merely naming an operant quadrant.
