Dogs, regardless of breed, can face serious health risks in hot weather if not properly cared for. Heat-related illnesses such as dehydration, heat exhaustion, and heat stroke can occur, potentially leading to severe health complications or even death. Flat-faced breeds are particularly vulnerable due to their difficulty in regulating body temperature. Leaving dogs in hot cars or exposed to direct sunlight for extended periods is especially dangerous. Pet owners in warm or tropical regions should be vigilant about providing their dogs with adequate shade, hydration, and breaks from the heat to prevent these risks.
