With hemangiosarcoma, the pericardium fills up with blood due to rupture of the tumor. When the tumor occurs in the skin, a mass or lump can usually be felt in or under the skin. The mass may become ulcerated and bleed. When the tumor occurs in a bone, it can cause pain and discomfort.
Ear hematomas in dogs are usually caused when a dog shakes his head violently, resulting in the ear flaps banging against his head or into nearby firm objects. A dog that scratches at his ear flap or experiences some other trauma to it can also develop an aural hematoma. Most often, an underlying ear problem causes itchiness, pain, or discomfort to the dog, which results in him shaking his head hard or scratching at his ear.
