The dog amongst all the animals has proved to be the man's best
friend and faithful companion because of its fidelity, loyalty,
obedience and pleasant disposition. Dogs appeared on the earth
about 20 million years ago (Sharma et al., 1993). The dog's stomach
is a sac-like structure designed to store large volumes of food and
begin the digestive process. Once eaten, most food leaves the
stomach within twelve hours after entering. The esophagus carries
food to the stomach, where it enters via a valve-like structure
called the cardiac sphincter. On the interior surface of the
stomach is a series of folds called gastric folds. These folds
function to help grind and digest food. The inner stomach lining
secretes acids and enzymes to break food down as the initial step
in the digestive process. Once the initial stomach digestive
process is complete, the partially digested food exits the stomach
through the pyloric sphincter area and then enters the duodenum
(small intestine).
