Abstract
Helminth infections broke out collectively in dogs of a breeder's kennel in Hojo-shi, Ehime, Japan in January, 1987. Helminth eggs were detected in the feces of 20 (80%) of 25 dogs kept in the kennel. Eggs detected were of Trichuris vulpis in 17 dogs (68%), Toxocara canis in 4 dogs (16%), and Ancylostoma caninum in 13 dogs (52%). The heavy helminth infections in this kennel was considered to have been induced by such favorable conditions for the parasites to be easily transmitted among dogs as that these animals had often been kept on the muddy ground.
Febantel was orally administered to 20 dogs positive for helminth eggs at a dose of 10mg/kg/day for 3 consecutive days. After the treatment, eggs completely disappeared within a week from the feces of 16 of 17 whipworm-infected dogs, 3 of 4 roundworm-infected dogs, and all the 13 hookworminfected dogs. In the other two dogs the parasites were completely eliminated by the following another administration of the drug. From these results, febantel seemed to be an excellent anthelmintic for the canine intestinal nematodes.
