A Miniature Pinscher bitch was treated by the owner with enrofloxacin at dose of 50 mg/kg, once a day, for two days (daily dose rate 10 times greater than prescribed). Physical examination showed depression, lumbar cifosis, hipotermia, pale mucosa, dispneia, drewling, vomiting and anuria, followed by respiratory failure, seizures, and coma. Symptomatic treatment was performed, and the urinary flow returned to normal in 12 hours, and seizures were controlled. However, the animal stayed in coma, and died 72 hours after the beginning of the treatment. Acute renal and hepatic failure, and hipovolemic shock, compatible with enrofloxacin intoxication, were observed through necropsia and histopatology.
