Can myotonia congenita in dogs be cured?

Myotonia congenita is a lifelong condition — the chloride channel defect in muscles is genetic and permanent. There's no cure, but symptoms can be managed. The stiffness tends to be most pronounced in young dogs and may stabilize or even slightly improve with age and regular exercise. Medication can help in moderate to severe cases. Most affected dogs lead comfortable lives with good management. The condition isn't typically painful — it's more about mobility and awkwardness than suffering.
