Description    Dogs can develop meningitis that does not respond to antibiotic treatment but improves following corticosteroid therapy. CSF shows increased protein and neutrophilic pleocytosis. Waxing and waning neck pain and fever with a stiff, short-strided gait and reluctance to walk are the most common signs, but other neurologic deficits have been seen. This is the most-common form of meningitis diagnosed in most veterinary hospitals, and can be seen concurrently with immune-mediated polyarthritis.
