Establishing a prognosis for dogs with dominance-related aggression is difficult. Some dominant-aggressive dogs respond well to treatment; others continue to be serious risks for their owners. A study was performed to identify characteristics of dominance-related aggression and to identify risk factors associated with whether the aggressive behavior led to euthanasia. Medical records of 110 dogs with dominance-related aggression were examined retrospectively; characteristics of owner-directed aggression and eventual outcome of the dogs were recorded. By means of logistic regression, 2 different models were found to describe the association between behavior characteristics and outcome. In the first model, severe aggression in response to benign dominance challenges and body weight > 18.2 kg were associated with outcome. In the second model, unpredictability of aggression and a history of being purchased were associated with outcome. We concluded that dominance-related aggressive behavior can be subclassified according to severity and type and that outcome (ie, euthanasia) may be predictable in some cases.
对患有与支配欲相关攻击性的犬只进行预后评估很困难。一些具有支配欲攻击性的犬只对治疗反应良好；而另一些则继续对其主人构成严重风险。开展了一项研究，以确定与支配欲相关攻击性的特征，并确定与攻击行为是否导致安乐死相关的风险因素。对110只患有与支配欲相关攻击性的犬只的病历进行了回顾性检查；记录了针对主人的攻击行为特征以及犬只的最终结局。通过逻辑回归分析，发现了2种不同模型来描述行为特征与结局之间的关联。在第一个模型中，对良性支配挑战的严重攻击行为以及体重>18.2千克与结局相关。在第二个模型中，攻击行为的不可预测性以及被购买的历史与结局相关。我们得出结论，与支配欲相关的攻击行为可根据严重程度和类型进行分类，并且在某些情况下结局（即安乐死）可能是可预测的。
