Abstract：
Heat Related Illness (HRI) in dogs is expected to increase as heatwaves surge due to global warming. The most severe form of HRI, heat stroke, is potentially fatal in dogs. The current study investigated the incidence and risk factors for HRI in dogs in NSW, Australia, from 1997 to 2017. We identified 119 HRI cases during this period, with a fatality rate of 23%. Dog breeds at elevated risk of HRI were Australian Stumpy Tail Cattle Dog, British Bulldog, French Bulldog, Maremma Sheepdog, Italian Greyhound, Chow Chow, Airedale Terrier, Pug, Samoyed, English Springer Spaniel, Labrador Retriever, Golden Retriever, Cavalier King Charles Spaniel, Border Collie, Staffordshire Bull Terrier, and pooled non-Australian National Kennel Council breeds (which included the American and Australian Bulldog) when compared with cross breeds (i.e., the reference variable). As expected, HRI cases were more likely in December and January, during the Australian summer and during hotter years (e.g., 2016). There were no differences in the risk of HRI between males and females nor between desexed or un-desexed dogs; but older dogs were at increased risk of HRI. These findings underscore the need for data collection that will enable the incidence of HRI in dogs to be monitored and to better understand canine risk factors particularly as temperatures will continue to rise due to global warming. The risk of mortality from HRI underpins the need for education programs focussed on prevention and early identification of HRI so that owners present affected dogs to their veterinarian as promptly as possible.
摘要：
随着全球变暖引起的热浪激增，狗的热相关疾病（HRI）预计会增加。最严重的HRI形式，中暑,在狗中可能是致命的。本研究调查了新南威尔士州犬HRI的发生率和危险因素，澳大利亚,从1997年到2017年。在此期间，我们确定了119例HRI病例，死亡率为23%。HRI风险较高的犬种是澳大利亚短尾牛犬，英国斗牛犬,法国斗牛犬,马雷玛牧羊犬，意大利灰狗,ChowChow,AiredaleTerrier,帕格,Samoyed,英国斯普林格猎犬，拉布拉多猎犬,金毛猎犬,骑士国王查尔斯猎犬，边境牧羊犬，斯塔福德郡斗牛犬，与杂交品种(即，参考变量)。不出所料,HRI病例更有可能在12月和1月，在澳大利亚夏季和炎热的年份(例如，2016)。HRI的风险在雄性和雌性之间以及在分离或未分离的狗之间没有差异；但是年龄较大的狗患HRI的风险增加。这些发现强调了数据收集的必要性，这将使犬HRI的发生率得到监测，并更好地了解犬的危险因素，特别是由于全球变暖，温度将继续上升。HRI的死亡风险支撑了对教育计划的需求，该计划侧重于HRI的预防和早期识别，以便主人尽快向兽医介绍受影响的狗。
