Abstract

Toxocara canis (Werner, 1782) is the round worm most frequently found in dogs. From surveys in the United States, approximately 40-100% of young dogs and 5-70% of older dogs are infected with this parasite. Of 97 adult dogs surveyed in Provo, Utah, in 1968, 17. 5% were infected with T. canis (Fox, personal communication). Adult dogs become infected by ingesting food contaminated with the infective eggs from this parasite. Puppies are most frequently infected prenatally from their mother (Nifontov, I 949; Yutuc, 1949; Sprent, 1958; Webster, I 958; Douglas and Baker, 1959; Scothorn, Koutz and Groves, 1965; Wiseman. 19 69).
