Which of the following comprises the three dimensions used to assess animal welfare?

• A. Size, color, speed
• B. Valence, intensity/severity, duration
• C. Age, breed, sex
• D. Welfare priority, urgency, risk

Answer: (B)

Welfare is described by three dimensions: valence, intensity or severity, and duration. Valence is about whether the animal’s experience is positive or negative—the hedonic quality of what the animal feels. Intensity or severity measures how strong that experience is, from mild discomfort to severe pain. Duration looks at how long the animal experiences that state, recognizing that longer lasting states can have a bigger impact on overall welfare. These three aspects work together to capture the full picture of welfare: the type of feeling (positive or negative), how powerful it is, and how long it lasts. For instance, a brief, mild discomfort has different welfare implications than prolonged, intense pain. The other options refer to physical traits, demographics, or risk assessments, which do not describe the experiential dimensions used to evaluate welfare in this framework.
