−

*Adult worms live in the [[Lungs Circulatory - Pathology|pulmonary arteries]] and '''right side of the heart''' dogs and foxes

−

*Cause a proliferative endoarteritis

−

*More severe damage is caused however by eggs lodging in arterioles and capillaries

−

*In severe infection, this can result in [[Lungs Inflammatory - Pathology#Infectious causes of pneumonia|pneumonia]] and [[Lungs Circulatory - Pathology#Pulmonary oedema|pulmonary oedema]] as an acute syndrome

−

*Circulatory impedance can result in congestive cardiac failure

−

*Particularly a problem if dogs eats snails

−

*Gross:

−

**Patchy white appearance with haemorrhagic areas within

−

*Microscopically:

−

**Golden pigment within macrophages (haemosiderin)

−

**Inflammation and scarring of alveolar walls -> enlargement of remaining air spaces

−

*Worms secrete anticoagulant -> haemorrhage in other parts of body

−

*May present as neurological cases due to the haemorrhage

−

*May cause [[Lungs Circulatory - Pathology#Embolism, thrombosis and infarction|pulmonary thromboembolism]]
