Dog Digestive SystemThe Dog Digestive System is composed of all the necessary organs so that a complete digestion can take done, beginning in the moment when the food is ingested and chewed until the moment that they are processed and turned into energy, which are later expelled as residue. Beginning at the mouth and ending at the anus. The food must reach the stomach as a skittle, with the help of chewing, the tongue and saliva; it is then passed through the esophagus to the stomach, where the food is digested, and the fluid mass will then pass to the small intestine.Finally the wastes pass to the large intestine where they are turned into feces, which then pass through the rectum to the anal opening.
