Your dog's liver secretes a fluid called bile that plays a vital role in the digestion of food in the stomach and the removal of waste along the digestive tract. Bile moves from the liver to the gallbladder, and once food moves into your dog's small intestine, bile is released into the small intestine to help break down food particles and emulsify the waste that cannot be used by the body.
