How do dogs digest food?

Answer 1

I've found this article about digestive system of dog…

Dogs digestive is, mainly, that of a carnivore, the most distinct characteristic being the voluminous stomach and shorter intestinal length indicative of a carnivore. This helps in rapid digestion of raw meat. The entire anatomy of the dog is adapted for a raw meat diet.

The dog stomach has a voluminous capacity and plays the largest role in the digestive process (it makes up 60-70 percent of the total volume of the digestive tract, the herbivore less than 30 percent) and is where the majority of protein, i.e., meat, digestion takes place. Food stays in the stomach for up to eight hours, as opposed to the herbivore's 2-3 hours. This ensures the meat is well broken down before entering the intestinal tract where toxins released by putrefying meat could be absorbed; it secretes large amounts of hydrochloric acid (ten times more than the herbivore) creating the highly acidic stomach environment necessary for digesting meat protein and killing any dangerous bacteria that may have been ingested. The carnivore small intestine is short (3-6 times body length) compared to the herbivore at 10-12 times the body length.

Answer 2

Dogs digest food through a process that begins in the mouth with chewing and saliva production, then moves to the stomach where digestive enzymes and acids break down the food. The nutrients are absorbed in the small intestine, and waste is eliminated through the large intestine and rectum.
