I have been asked about an auto-immune disease called masticatory muscle myositis ( MMM)

It is a condition that shows up when young puppies have problems opening thir mouths.

Rod Russell has information on his site..........

Has any one had a cavalier with this problem? PM me if you do not want to give details on the list.
