Filaroides hirthi infection was diagnosed in 2 related Yorkshire Terriers. Dog 1 had a chronic nonproductive cough, but results of fecal flotation examination were negative. Dog 2 was a 1-year-old female progeny of dog 1. Both dogs came from the same kennel and were raised together for 8 weeks. Dog 2 had generalized demodicosis accompanied by secondary bacterial infection and had been treated with corticosteroids. Dog 2 also was given 68 micrograms of ivermectin, PO, and then 50 mg of fenbendazole/kg, PO, q 24 h for 14 days. After the 14-day treatment, results of 3 fecal examinations were negative for Filaroides sp and other parasites, and the dog improved without complications. Fecal examination of the other dogs in the kennel were negative for F hirthi.
