Heat stroke in dogs can be fatal if not prevented. Large breeds, flat-faced dogs, and those with pre-existing health conditions are at higher risk. Prolonged exposure to high temperatures, hot pavement, and lack of hydration can lead to severe health complications. Pet owners are advised to monitor their dogs closely for signs of overheating, such as excessive panting, drooling, or lethargy. The risks are particularly high during heat waves, making it crucial to limit outdoor activities and ensure pets have access to cool, shaded areas.
