Verminous pneumonia due to Filaroides hirthi in a Scottish terrier in Spain.

ABSTRACT

A previously healthy Scottish terrier developed verminous pneumonia due to Filaroides hirthi. The disease was diagnosed on the basis of cytology of a transtracheal wash, which contained 17 per cent eosinophils and a large number of parasite larvae. Treatment with 50 mg/kg bodyweight fenbendazole daily for three weeks eliminated the parasites and improved the clinical condition of the dog.
