A male Beagle dog weighing 9.5kg and estimated to be 5 years of age was presented to the authors' clinic in July, 1971. Paralysis appeared in its hind quarters in September, 1969. It cut itself by selfabuse in such manner in December, 1969, that it had no portion distal to the middle of the metatarsus of the right leg. The cut wound had been healed and locomotion was possible.
Physical examination revealed a decrease in skin temperature in the lower portions of both legs. No pulse was felt at the femoral artery. Roentgenography disclosed arterial embolemia in the leg. The intradermal test was positive. In conclusion, the dog was diagnosed as a case of inveterate paradoxical embolemia caused by canine filariae and accompanied by an open condition of the foramen ovale. The diagnosis was verified by autopsy and histopathological examination.
