Spina bifida in the dog

Abstract

Spina bifida was diagnosed in four English Bulldogs and one Collie dog. These cases and the examination of records from the Veterinary Medical Data Program suggested a high incidence of spina bifida in the English Bulldog. Urinary and fecal incontinence was the most common reason for initial examination for the five dogs. Radiographs and myelography confirmed the diagnosis of spina bifida. Blood, cerebrospinal fluid and urine analysis did not aid diagnosis but urocystitis was identified. In addition to spina bifida, clinical signs and morphologic changes in the spinal cords of all five dogs fulfilled the criteria for an additional diagnosis of spinal dysraphism. A common pathogenesis for the two conditions is suggested.
