We report a case of acute-onset ambulatory par-aparesis with electrophysiological abnormalities compatible with axonal and demyelinating lesions in a Rottweiler dog. Although the clinical findings were compatible with acute canine idio-pathic polyneuropathy, postmortem investigations revealed a chronic demyelinating polyneuropathy affecting the nerve roots. Due to the combination of acute clinical presentation and chronic pathologic features, this case is consistent with the acute-onset form of chronic inflammatory demyelinating poly-neuropathy (A-CIDP). © 2010 Wiley Periodicals, Inc.
