Myasthenia gravis in dogs is an immune-mediated disorder disrupting the nerve-muscle junction, causing profound weakness that requires careful long-term management.
Dogs with MG suffer from severe weakness that can leave them unable to walk or swallow safely. Megaesophagus causes chronic regurgitation, creating constant discomfort and aspiration risk. Affected dogs need special feeding positions (Bailey chair upright feeding) and close monitoring. The disease creates stress for both the animal and the caregiving family, and quality of life assessment must be ongoing.
