Glanzmann's Thrombasthenia Type I
A disease of defective platelet aggregation, this causes affected dogs to bleed excessively in response to mild tissue trauma. Normally, platelets clump ("aggregate") together and form a plug at the site of injury. Dogs affected with Glanzmann’s thrombasthenia are unable to aggregate their platelets.
