In Review — Pending Editorial Approval

What It Means in Practice

If a dog has a negative experience with a stimulus, repeated exposure can make the response stronger, not weaker. The dog becomes more sensitive, not less.

What It Does Not Always Mean

Sensitization is not the same as stubbornness or regression. It is a natural learning process where the dog's response intensifies.

Why Context Matters

Sensitization is the opposite of habituation. Whether a dog habituates or sensitizes depends on the nature of the stimulus and the dog's experience.

Commonly Confused With

Habituation

Habituation reduces response to neutral stimuli. Sensitization increases response to stimuli that have become threatening.
