What is NOT a sign of heat stroke in dogs?

Excessive woofing is not recognized as a sign of heat stroke in dogs. Heat stroke primarily involves physiological responses to overheating, which manifest through symptoms that directly relate to the dog's physical state.

Extreme thirst, vomiting, and a bright red tongue are all significant indicators of a dog suffering from heat exhaustion or heat stroke. Extreme thirst occurs as the body seeks to cool down and restore hydration levels. Vomiting is a reaction to the distress that heat stroke places on the body, often due to dehydration or overheating. A bright red tongue indicates increased blood flow and overheating, showing that the dog's temperature regulation is failing.

In contrast, excessive barking or "woofing" does not directly correlate with the signs of heat stroke. It may be a dog's response to stress or discomfort but is not a definitive physiological indicator of overheating. Understanding these signs is crucial for recognizing heat stroke, especially in warm environments or during vigorous exercise.
