Which clinical sign supports immune-mediated thrombocytopenia in a dog or cat?

Explanation:
Low platelets from immune-mediated destruction impair primary hemostasis, so the ability to form a platelet plug at sites of small vessel injury is reduced. This leads to spontaneous or easily provoked bleeding on mucosal surfaces, such as the gums, nose, or conjunctiva, and often to petechiae or ecchymoses. Because mucosal bleeding is a classic, direct sign of low platelets, it strongly supports immune-mediated thrombocytopenia in dogs and cats. Terms like hemoptysis can occur with bleeding but are less characteristic, while seizures and polyuria point to other problems not related to platelet count.
