'''Eosinophilic Myositis''' is a rare disorder of dogs causing immune-mediated inflammation of the muscles of mastication.
==Signalment==
The '''average''' age of affected dog is 3 years old. Seen most commonly in '''German Shepherds''' and '''Weimaraners''', there is no recorded sex predilection.
==Clinical Signs==
Bilateral symmetrical swelling of masseter, pterygoid and temporal muscles
Exopthalmos
Chemosis/eyelid odema
Third eyelid protrusion
Pain on opening jaws fully
A key difference from other orbital disease is that the clincial signs are '''bilateral'''
==Diagnosis==
Muscle biopsy provides definite diagnosis
==Treatment==
Immunosuppressive doses of [[steroids]], azathioprine if needed.
Recovered animals may have permanent difficulty opening their jaws due to muscle scarring.
