Heat-related illness will affect increasing numbers of dogs as global temperatures rise unless effective mitigation strategies are implemented. This study aimed to identify the key triggers of heat-related illness in dogs and investigate canine risk factors for the most common triggers in UK dogs. Using the VetCompass^TM programme, de-identified electronic patient records of 905,543 dogs under primary veterinary care in 2016 were reviewed to identify 1259 heat-related illness events from 1222 dogs. Exertional heat-related illness was the predominant trigger (74.2% of events), followed by environmental (12.9%) and vehicular confinement (5.2%). Canine and human risk factors appear similar; young male dogs had greater odds of exertional heat-related illness, older dogs and dogs with respiratory compromise had the greatest odds of environmental heat-related illness. Brachycephalic dogs had greater odds of all three types of heat-related illness compared with mesocephalic dogs. The odds of death following vehicular heat-related illness (OR 1.47, p = 0.492) was similar to that of exertional heat-related illness. In the UK, exertional heat-related illness affects more dogs, and kills more dogs, than confinement in a hot vehicle. Campaigns to raise public awareness about heat-related illness in dogs need to highlight that dogs don’t die just in hot cars.

狗不会仅仅在炎热的汽车中死亡 - 与热有关的疾病（中暑）对英国狗来说是一个更大的威胁。

随着全球气温上升，除非采取有效的缓解策略，否则与热有关的疾病将影响越来越多的狗。这项研究旨在确定狗中热相关疾病的关键触发因素，并调查英国狗中最常见触发因素的危险因素。使用 VetCompass ^TM程序，对 2016 年接受初级兽医护理的 905,543 只狗的去识别化电子患者记录进行了审查，确定了 1222 只狗的 1259 起与高温相关的疾病事件。劳累性热相关疾病是主要触发因素（占事件的 74.2%），其次是环境限制（12.9%）和车辆限制（5.2%）。犬类和人类的危险因素似乎相似；年轻的公狗患与劳力性热相关疾病的可能性更大，年长的狗和患有呼吸系统疾病的狗患环境热相关疾病的可能性最大。与中头犬相比，短头犬患所有三种与热有关的疾病的几率更大。车内热相关疾病的死亡几率（OR 1.47，p = 0.492）与劳累性热相关疾病相似。在英国，与被关在热车里相比，与劳累性高温相关的疾病影响更多的狗，并导致更多的狗死亡。提高公众对狗与热相关疾病的认识的活动需要强调狗不会仅仅在炎热的汽车中死亡。
