RESUMO
Descreveram-se os achados clínicos e patológicos de um caso de displasia renal em um cão da raça Rotweiller com oito meses de idade. O animal apresentou vômitos, emagrecimento, polidpsia e poliúria. Houve elevação sanguínea de creatinina, cálcio e da fosfatase alcalina. À necropsia, notaram-se os rins diminuídos de tamanho, com estruturas císticas proeminentes sobre a superfície natural do órgão e, ao corte, firmes e com estruturas císticas distribuídas pelo parênquima. Na avaliação histológica, havia glomérulos imaturos, fibroplasia intersticial e dilatação cística tubular.
