Companion Dog Myasthenia Gravis Welfare

Management of myasthenia gravis in dogs, an autoimmune condition causing muscle weakness and risk of aspiration pneumonia.

Key Facts

Myasthenia gravis causes progressive muscle weakness including esophageal dilation in dogs
Regurgitation and aspiration pneumonia are the most significant welfare concerns
Anti-acetylcholinesterase drugs can improve neuromuscular junction function in affected dogs
Upright feeding using a Bailey chair prevents regurgitation and aspiration
Spontaneous remission occurs in a proportion of dogs with acquired myasthenia gravis

Welfare Considerations

Myasthenia gravis causes progressive weakness and the life-threatening risk of aspiration pneumonia from regurgitation. Management through elevated feeding positions and appropriate medication can maintain quality of life substantially. Owner commitment to intensive management is essential.

What You Can Do

Seek specialist neurology assessment for dogs with progressive muscle weakness
Implement upright feeding immediately on diagnosis and maintain consistently
Monitor for signs of aspiration pneumonia and seek emergency care if breathing changes
