Abstract
A one-year-old male Dachshund (Miniature Smooth-haired, light brown hair, weighing 3.7 kg) with clinical signs of myalgia and astasia was diagnosed with polymyositis based on clinical signs such as an abnormal nee-dle electromyogram (fibrillation potential and positive sharp waves) and marked elevation of creatine phos-phokinase activity. The dog also had exocrine pancreatic insufficiency (EPI). The condition improved rapidly with aggressive administration of prednisolone and pancreatic enzyme replacement therapy.
