O presente trabalho refere-se a determinação da densidade urinária e dosagem sérica de uréia e creatinina em cães submetidos a aflatoxicose experimental. Foram utilizados 14 cães (7 machos e 7 fêmeas), sem raça definida, adultos e peso médio de 6,7 ± 1,96kg. Em um período pré-experimento foram realizadas 3 colheitas de urina e sangue de cada animal para avaliação da função renal e as médias das determinações foram utilizadas como controle. Os cães receberam 6 7µg/kg/dia de aflatoxina, via oral, durante 9 dias consecutivos. A partir do quinto dia foram realizadas 4 colheitas com intervalos de 5 dias. Os resultados obtidos demonstraram, através dos sinais clínicos e das lesões macro e microscópicas, o desenvolvimento de aflatoxicose, sendo que não houve alteração na função renal detectável através dos parâmetros estudados. The objective of the present work was to evaluate plasma levels of urea and creatinine and urine density in dogs using experimentally induced aflatoxicosis. Fourteen adult mongrel dogs (7 males and 7 females), weighing 6.7 ± l.96kg were treated with oral aflatoxin (67/µg/kg/day) during 9 days. Three control blood and urine samples were collected before the begining of experimental trial. Then starting on the 5th day of treatment, another 4 samples were collected with 5 day intervals. The results showed that aflatoxin at the dosage used produced clinical signs of intoxication, which later were confïrmed by histopathology. However, no alteration in the renal profile could be detected by standard clinical pathology
