Heat stress is a rapidly life-threatening emergency for companion animals, particularly dogs, with prevention through owner education the most effective welfare intervention.
Dog heat stress welfare is an area where owner education directly prevents acute suffering and death. The physiological constraints of dogs - limited to panting for cooling, with brachycephalic breeds especially compromised - create situations where rapid temperature elevation causes life-threatening hyperthermia. Leaving dogs in hot cars, exercising in midday heat, or confining dogs without shade and water can all cause acute welfare emergencies within minutes. The prevention message is clear and actionable: recognise the signs, avoid high-risk situations, and respond immediately to suspected heatstroke with cooling rather than waiting for veterinary arrival.
