This is a congenital muscle disorder where the muscle fibers responsible for endurance (type 1 fibers) are abnormally smaller than those used for quick power (type 2 fibers). This disproportion impairs normal muscle development and function across the body. Currently, this condition cannot be detected with a genetic test and can only be diagnosed by examining a muscle tissue sample, known as a biopsy, under a microscope.
Symptoms usually become noticeable during puppyhood. Owners may observe general muscle weakness, a stiff or clumsy way of walking, quick tiring during play, and potential difficulties with swallowing or breathing.
There is no cure for this lifelong condition, so management focuses on supportive care like physiotherapy to maintain mobility. Lifetime treatment and supportive care typically cost between €1,500 and €6,000.
Estimated range of typical treatment cost. Actual cost depends on severity, clinic and region.
