Similarly, the time that it will take for your dog to digest his food also depends upon what type of food he eats. Generally speaking, raw food and canned food will move through his system faster than dry food; it typically takes between 4 and 6 hours for a dog to process a meal's worth of canned food. On the other hand, it may take as many as 8 to 10 hours for the same dog to process dry food completely. Other Factors
When it comes to our digestive system, it can take hours or even longer for food to pass through. That's what it takes for the body to get the nutrients and energy it needs from what you ingest. It usually takes from 24 to 72 hours for healthy people to completely digest food and eliminate waste products. The first stop for food is the esophagus, which moves food from the back of the throat to the stomach. About six to eight hours after eating, food passes through the stomach and small intestine.
