Dog Canine Myasthenia Gravis Welfare

Myasthenia gravis causes progressive muscle weakness in dogs - appropriate management maintains quality of life and prevents aspiration pneumonia.

Key Facts

Acquired myasthenia gravis is an autoimmune condition destroying neuromuscular junction receptors
Megaoesophagus secondary to MG causes regurgitation and aspiration pneumonia risk
Bailey chair feeding (upright position for 20 minutes after meals) prevents aspiration
Pyridostigmine improves neuromuscular transmission and muscle strength
Spontaneous remission occurs in 50% of cases within 6-18 months with appropriate management

Welfare Considerations

Myasthenia gravis causes progressive weakness and aspiration risk that significantly compromises welfare. Bailey chair feeding prevents the most serious complication, while medical management improves muscle function. Spontaneous remission in many cases provides real hope for affected dogs.

What You Can Do

Invest in a Bailey chair if your dog has MG with megaoesophagus
Administer pyridostigmine consistently and monitor response carefully
Be aware of aspiration pneumonia signs and seek immediate care if coughing develops
