Data on over 222,000 Swedish dogs enrolled in life insurance in 1992 and 1993 were analysed. There were approximately 260 deaths per 10,000 dog-years at risk. Breed-specific mortality rates and causes of death are presented for breeds with more than 500 dogs at risk that had consistently high or low rates. Breed-specific mortality ranged from less than 1 per cent to more than 11 per cent. True rates and proportional statistics for the cause of death were calculated for the entire insured population (250 breeds) and cause-specific mortality rates were calculated for the breeds with the highest risk of dying of the most common causes. Trauma, tumours and problems related to the locomotor system together accounted for more than 40 per cent of all deaths or euthanasias. Although limited to insured dogs, these data cover approximately one-third of all Swedish dogs and provide baseline mortality data for further population-based studies on health and disease.
对1992年和1993年参加人寿保险的22.2万多只瑞典犬的数据进行了分析。每10000犬年的风险中约有260例死亡。针对风险犬只数量超过500只且死亡率持续偏高或偏低的品种，列出了特定品种的死亡率和死亡原因。特定品种的死亡率从不到1%到超过11%不等。计算了整个参保犬群（250个品种）的真实死亡率和死因比例统计数据，并针对因最常见原因死亡风险最高的品种计算了特定病因死亡率。创伤、肿瘤和与运动系统相关的问题合计占所有死亡或安乐死病例的40%以上。尽管这些数据仅限于参保犬只，但涵盖了约三分之一的瑞典犬，为进一步开展基于人群的健康与疾病研究提供了基线死亡率数据。
