Which of the following is included in Step 4 of the Humane Hierarchy?

• A. Extinction
• B. Positive Punishment
• C. Positive Reinforcement
• D. Health, nutrition, physical factors

Answer: (A)

Extinction sits in Step 4 because it uses the least intrusive approach that directly reduces a behavior by removing the reinforcement that sustains it. When you apply extinction, you withhold all rewards or attention the dog receives for the undesired behavior, so that behavior is no longer reinforced and should gradually cease. This works best after you have already set up the environment to reduce triggers (antecedents) and have taught or reinforced an appropriate alternative behavior so the dog has a better option.Be mindful that an extinction burst can occur—briefly, the undesired behavior may spike before it declines—so consistent management is essential to prevent any hidden reinforcement and to keep the process safe and humane. Positive reinforcement and positive punishment represent other approaches; the former focuses on building and rewarding desired behavior, not extinction, while the latter uses aversives and is not the method used in this stage. Health, nutrition, and physical factors are important to check early to rule out medical causes, not a behavioral technique used at this stage.
