Myasthenia gravis in the dog

Abstract

An account is given of four cases of myasthenia gravis in the dog. All animals showed fatigue, and considerably reduced tolerance to exercise. Recovery followed rest or treatment with neostigmine. Three animals, two of which are still alive, had dilatation of the oesophagus. The fourth eventually died from an aortic body tumour. The occurrence of myasthenia in the dog may be of value in elucidating the cause of the disease in man.
