Ordinary bacterial gastroenteritis in dogs does not lead to death. Acute gastroenteritis usually turns into chronic gastroenteritis with clinical manifestations such as indigestion and wasting, but there is also a risk of death if left untreated. Some diseases also manifest as gastroenteritis, such as microviruses and coronaviruses, with microviral infections having a higher mortality rate. Prompt diagnosis and treatment at a hospital is recommended.
