Under the 1985 amendment, the manner of exercise for dogs must be determined by whom?

• A. A veterinarian
• B. The IACUC
• C. The facility manager
• D. The principal investigator

Answer: (A)

The exercise plan for dogs in research is determined by a veterinarian because the welfare of the animals requires clinical judgment about their physical and behavioral needs. A veterinarian has the training to assess each dog’s health, stress levels, and activity requirements, and to tailor an exercise regimen that supports well-being and aligns with the study’s goals. The IACUC oversees and approves animal care and use, but the specific manner of exercise is based on veterinary expertise. The principal investigator designs and conducts the study and may set overall protocol elements, but they rely on the veterinarian to specify how exercise is actually provided. The facility manager handles daily operations and logistics, not the determination of the exercise method itself.
