With the objective to determine T. vulpis by oral inoculation with maximum 1,500 eggs; dogs had been infected with 500, 1,000 and 1,500 larvae eggs. From sixth week after infection, the egg counting was carried through eggs per gram of feces (EPG) of each dog and from 11ª week egg elimination was observed in feces. The first Dog received 500 eggs and did not present eggs in feces; The second dog received 1000 eggs and presented a EPG of 17.150 in 12ª week with oscillations of up to 1,150 in 18ª week. Dog 3 that it received 1,500 eggs presented 50 EPG and reached the maximum of 150 eggs in 28ª week. In this study it can be concluded that the dose of 1.000 and 1.500 eggs of T.vulpis was capable to infect the dogs and that the dose of 1,000 eggs can be indicated to keep the experimental cycle.</p> ER -
