What does this mean for a dog with this trait?

Centronuclear myopathy cannot be cured, though its symptoms may be managed through physical therapy, weight management, and supportive devices to help with mobility and stability.

Symptoms

Symptoms of centronuclear myopathy typically present between 2 and 5 months of age. They include a progressive loss of muscle strength, exercise intolerance, and an awkward gait.
