Hemothorax refers to the presence of frank blood in the thorax.
In dogs, this is commonly associated with:
- Acute chest trauma
- Anticoagulant rodenticides
- Hemorrhagic pneumonia associated with Streptococcus equi subsp. zooepidemicus
- Spirocerca lupi granuloma rupture
- Angiostrongylus vasorum
These cases should be treated as medical emergencies and usually require chest drainage, with transfusion or autotransfusion if applicable.
