What describes a moderate heat injury?

• A. Very high 106-108 rectal temperature, uncontrolled panting, fast strong or weak pulse, loss of appetite, ignores handler, bright red mucous membranes.
• B. Mild panting and thirst.
• C. Seizures and unconsciousness.
• D. Normal appetite.

Answer: (A)

Recognizing heat illness in dogs hinges on how high the body temperature is and how the dog is behaving under stress. A rectal temperature in the range of 106–108 F, combined with signs of distress like uncontrolled panting, a rapid or weak pulse, loss of appetite, a change in behavior such as ignoring the handler, and bright red mucous membranes, shows the body is struggling to dissipate heat and organs are under strain. That mix of a markedly elevated temperature with multiple systemic signs indicates a significant heat injury, typically categorized as more than mild but not yet at the point of collapse or unconsciousness, which fits what’s described as a moderate heat injury.

Milder heat stress would present with only mild panting and thirst, without the pronounced temperature rise or systemic distress. Seizures or unconsciousness point to a severe, life-threatening heat stroke beyond moderate. Normal appetite would not reflect a dog actively affected by heat illness.
