Dogs, particularly breeds with thick fur or short snouts (brachycephalic breeds like Bulldogs and Pugs), are highly susceptible to heatstroke. Unlike humans, dogs primarily cool themselves through panting, which is a less efficient method when humidity is high. Their fur coats, while providing insulation in winter, can become a liability in the scorching heat. Overexertion during walks or playtime can quickly lead to overheating, making it essential to limit outdoor activities during peak heat hours.
