What signs would indicate heat stress risk in a dog during conditioning in hot environments?

• A. Normal thirst and normal heart rate.
• B. Rapid breathing, excessive panting, lethargy, or signs of collapse.
• C. Increased appetite and energy.
• D. Sleeping through heat.

Answer: (B)

During conditioning in hot environments, signs of heat stress risk reflect the body's struggle to regulate temperature. Rapid breathing or excessive panting shows the dog is trying hard to cool off, and when this is paired with lethargy or signs of collapse, it indicates heat load is overwhelming the dog’s ability to dissipate heat. This combination is a clear warning that exercise should stop, the dog should be moved to shade, and cooling measures should be started and monitored closely. Normal thirst and normal heart rate suggest no immediate distress. Increased appetite and energy imply the dog is not experiencing heat stress, and sleeping through heat does not reliably signal safety during conditioning.
