This study aimed to identify the causes of death in dogs that were buried at pet cemeteries. Using data obtained from a questionnaire completed by 5,118 dog owners from 1 April 2016 to 31 March 2017, we estimated the life expectancy and the odds ratio for principal causes of death using multiple logistic regression analysis with potential risk factors as independent variables. The life expectancy determined at birth was 13.98 years. The commonest cause of death was senility. The odds ratios of dying of senility being significantly higher in Labrador Retrievers and Shiba breeds and aged dogs, and significantly lower in Chihuahuas, dogs living indoors and neutered dogs.
本研究旨在确定埋葬在宠物墓地的犬只的死因。利用2016年4月1日至2017年3月31日期间5118名犬主填写的问卷所获数据，我们以潜在风险因素作为自变量，通过多元逻辑回归分析估计了预期寿命和主要死因的比值比。出生时确定的预期寿命为13.98岁。最常见的死因是衰老。拉布拉多猎犬、柴犬和老龄犬死于衰老的比值比显著更高，而吉娃娃犬、室内饲养犬和绝育犬死于衰老的比值比显著更低。
