How long can a dog with myocarditis live?

A dog with myocarditis has a low survival rate, and some sick dogs die within 24 hours of onset, so timely treatment is essential. Dogs rarely develop myocarditis on its own; it usually follows an infectious or parasitic disease. The treatment principle is to reduce the heart’s burden, improve myocardial nutrition, strengthen contraction, and treat the primary disease, while the dog needs quiet, careful nursing. However, if the dog has viral myocarditis, it is generally incurable.
