About 10 hours
Varying Factors. Your dog's digestion rate isn't affected by his size as much as by other factors, including the type of food you give him, the amount of exercise he gets, the amount of water he drinks and more. For example, an average dog -- big or small -- takes between four and six hours to digest canned wet food. Digesting dry kibble, on the other hand, may take between eight and 10 hours. 15-30 minutes for food. 10 minutes for just water. It actually takes much longer to digest food...closer to 10-12 hours for most dogs, about half that for puppies. You may notice your dog needs to go to the bathroom 15-30 minutes after eating, but that's just them relieving themselves of waste from a previous meal. The broken-down food will remain in the small intestine for up to about two days, depending on how difficult it is to break down further. Simple food, such as corn, will pass in a matter of a few hours, but bone or more complex material takes quite a bit longer. Generally, it takes between seven and 10 hours for a dog to digest food, but the many variables mean that only your vet can tell you how long it should be taking. Digestion time varies between individuals and between men and women. After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. 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. The amount of time it takes food to travel through your dog depends on multiple factors. The biggest one is the type of food your dog eats -- particularly, its quality and selection of ingredients and its fiber content. Factors like exercise also determine how long it takes for your dog to pass a bowel movement.
