Which of the following describes a symptom of heatstroke?

• A. Pale gums
• B. Bright red gums
• C. No panting
• D. Normal body temperature

Answer: (B)

Bright red gums reflect flushed mucous membranes from extreme overheating, a common sign of heatstroke. When a pet’s body is overwhelmed by heat, blood vessels near the surface dilate, making the gums appear very red as blood flow increases to help cool the body. This aligns with heatstroke symptoms.

Pale gums would point to poor perfusion or shock from other causes, not the intense overheating seen with heatstroke. Not panting at all would be unusual, since heavy or rapid panting is a primary way dogs (and many cats) try to cool down during overheating. Normal body temperature cannot match heatstroke, as the condition involves a dangerously elevated core temperature.

If heatstroke is suspected, act quickly: move the animal to a cooler shaded area, begin gradual cooling with lukewarm water, use a fan to help evaporation, and seek veterinary care immediately.
