Pet insurance for bloat (gastric dilatation and volvulus)
Emergency treatment for bloat is generally covered under accident and illness policies, because it is a sudden, life threatening event rather than a slowly developing illness. The main catches are that coverage must already be in force before the emergency and that a preventive stomach tacking operation, if done electively, is usually not covered.
What it is
Bloat, known medically as gastric dilatation and volvulus or GDV, is when a dog stomach fills with gas and can twist, cutting off blood flow, and it occurs mainly in large, deep chested breeds. Owners go to an emergency vet because of unproductive retching, a swollen belly, restlessness, or collapse, and the condition can become fatal within hours.
What treatment typically costs
Emergency surgery and treatment for a GDV case, with complications costing more typically runs $2,000 to $5,000 and up
