Answer: B - Giant breeds are the most susceptible type of dog to volvulus, a condition where the stomach rotates so that the pyloris and esophagus are occluded. This condition is life threatening. The most noticeable sign is the abdomen becoming distended as it is filled with food, water, or air. Deep chested breeds, such as Dobermans and German Shepherds, are also high risk.
