Although rare, some dogs can have extreme reactions to vaccinations. This should be reported to your vets office so they can place an incident report on the recurrence and also to run a parvo test to determine underlying causes. Maintain fluid intake, ge may again require hospital treatment if he becomes weak. Offer small, bland low fat meals to help protect the intestine
