Five dogs were presented with clinical signs compatible with upper airway obstruction, including stridor, stertor, coughing, gagging, and varying degrees of respiratory distress. All dogs had radiographic findings of soft tissue opacity in the area of the pharynx, larynx, or trachea, and several had narrowing of the tracheal lumen. Coagulation abnormalities (prolonged prothrombin time, activated partial thromboplastin time) were present in the four dogs that underwent testing. Four of five dogs were treated for the coagulopathy, presumably due to anticoagulant rodenticide toxicosis, and survived to discharge.Upper airway obstruction is an unusual presentation for anticoagulant rodenticide toxicosis in dogs. Raising the index of suspicion for this treatable condition may help clinicians to identify this sooner.
五只犬出现了与上呼吸道阻塞相符的临床症状，包括喘鸣、鼾声、咳嗽、作呕以及不同程度的呼吸窘迫。所有犬在咽部、喉部或气管区域的X光检查结果均显示软组织密度增高，几只犬还出现了气管腔狭窄。接受检测的四只犬存在凝血异常（凝血酶原时间延长、活化部分凝血活酶时间延长）。五只犬中有四只因疑似抗凝血灭鼠剂中毒导致的凝血病接受了治疗，并存活至出院。上呼吸道阻塞是犬抗凝血灭鼠剂中毒的一种不常见表现。提高对这种可治疗病症的怀疑指数可能有助于临床医生更早地识别它。
