The objective of this work was to evaluate the individual efficacy of the fenbendazole and the pyrantel pamoate against intestinal nematodes of dogs. Thirty six nestlings of dogs were used, being eighteen males and eighteen females up to six months of age, coming of the kennel of the Department of Veterinary Medicine of the Federal University of Viçosa, selected through fecal exams of Willis, simple sedimentation and count of eggs per gram of feces (EPG). being used the animals that presented mixed infection for Ancylostoma sp. and Toxocara canis. The animais were distributed in three groups of twelve animals, being a control group, a group treated with fenbendazole, 100 mg for Kg of body weight, orally, in an unique dose, and the other with pyrantel pamoate, 5 mg for Kg of body weight, orally, in an unique dose. During the whole experimental period, the dogs received commercial ration and water ad libitum . Fecal exams of Willis, simple sedimentation and EPG realized in the day of the treatment (0), 24 hours after the treatments (1) and in the 3, 5 and 7 after the treatments. In the seventh day, the animals were killed and necropsied for collection of the adult worms and the mucosa of the gastrointestinal tract was submitted to digestion process, in hydrochloric acid to 3%, for research of immature stages. The results showed an efficacy of 99,89% of the pyrantel pamoate against the A. caninum with reduction of 100% of EPG in the seventh day after the treatment, and against the T. canis the effectiveness was of 71,65%, with reduction of 80,73% of OPG. The fenbendazole showed an efficacy of 93,19% against the A. caninum, with reduction of 96,22% in the EPG and an efficacy of 82,1% against the T. canis, reducing the EPG in 95,71%. The results demonstrate the efficacy for the control of the A. caninum with the two drugs, with higher effective of the pyrantel pamoate. To the T. canis control the drugs shower lower efficacy when administered separately in the doses recommended commercially.
