Fecal incontinence, urinary incontinence, and priapism associated with multifocal distemper encephalomyelitis in a dog.

A 4-year-old castrated mixed-breed dog had atypical signs of chronic distemper encephalomyelitis. The predominant signs were related to visceral rather than somatic dysfunction. The visceral dysfunction was largely attributable to distemper-associated inflammatory lesions in the spinal cord and resulted in fecal incontinence, urinary incontinence, and priapism. Empirical treatment of the dog resulted in transitory improvement prior to euthanasia performed because of the progressive nature of the encephalomyelitis.
