What should I do if my dog has myotonia congenita?

While there's no cure, supportive care makes a real difference. Regular, gentle exercise helps reduce stiffness — short, frequent walks are better than occasional long ones. Avoid letting your dog get cold, as cold exacerbates muscle stiffness. Warm-up periods before activity help. Some vets prescribe muscle relaxants (like mexiletine) for more severely affected dogs. Keep your dog at a healthy weight to reduce strain on stiff muscles. Avoid situations that require sudden movement. Most dogs with myotonia congenita adapt well and live happy lives. Our vets can discuss whether medication would help your dog's specific case.
