Unexplained bleeding was the primary clinical complaint in 15 dogs diagnosed with A. vasorum and was observed in the mouth, as external bleeding, as large subcutaneous hematoma, as hemoptysis, in the brain, post ovariectomy, as epistaxis, in the anterior ocular chamber and on a tracheal intubation tube. In 8 dogs the cause of bleeding initially was suspected to be a minor trauma or a surgical complication, and various surgical approaches had been undertaken to eliminate the problem. In only 3 dogs respiratory signs were observed before the bleeding prompted referral. The median time elapsed between the first recognized clinical signs attributed to A. vasorum until diagnosis was 2 weeks (rangel day to 4 months). Four dogs died, 3 on the day of admission and 1 dog 4 days after admission. Suspected causes of death were respiratory failure and cerebral hemorrhage in 2 dogs each. Four dogs had been pre-treated with NSAIDs; of these, 2 dogs developed severe hemoptysis (1 died), 1 dog developed brain hemorrhage (and died), and 1 dog developed a large subcutaneous hematoma with marked anemia. Bleeding at various sites may be the only recognized abnormality in A. vasorum infection. Without a high index of suspicion, the diagnosis and appropriate therapy may be delayed to the point of a fatal outcome. Tests of coagulation were quite variable and the cause of bleeding likely multifactorial.
