How long does food stay in a dog’s stomach?
Though dogs are omnivores, they are opportunistic ones. That means that while they can eat almost anything, their digestive systems can’t break down and utilize everything. Animals like humans or cows, to name two, have GI tracts made to process plant matter. As a result, their intestines are much longer and more drawn out than those of dogs. Since cows depend on vegetable matter, they even get extra compartments in their stomach, and can regurgitate food to chew and digest it fully.
A dog’s digestive system, depending more on meat proteins, is much more efficient. Depending on its digestibility, food can stay in a dog’s stomach much longer than either a human or a cow. If the meal is not strictly meat, comprising a variety of vegetable, grains and proteins, it will have vacated the stomach completely in 12 hours after eating. Compare that to four to five hours in a normal adult human.
Where does digestion actually take place?
As you may have gleaned from tracing food’s intricate journey from the food bowl in your kitchen to the poop bag in the dog park, the multiple processes of canine digestion means that it does not happen in one spot. From the moment comestibles come in contact with teeth and saliva in the mouth, digestion is happening.
A dog’s digestive system is just that: a system, and digestion takes place at every point along the course. Food is disassembled in a variety of ways, physically and nutritionally, from the mouth to the stomach. The majority of its conversion into absorbable nutrients happens in the small intestine, and digestion is only complete when your dog assumes the familiar position for excreting waste.
How long does it take for a dog to digest food?
Finally, the question that got us started. Unfortunately, there’s no set answer! So many variables are involved, that even in a perfectly healthy dog, the time to digest a single meal can be dramatically different. Does your dog drink enough water? That has an effect on digestion time as well. Large dog breeds take significantly longer to digest food than small ones.
Is your dog sedentary, spending most of the day on the couch? Does the dog get a couple of walks a day? Exercise has a definite impact on motility, or the way that the muscles of the digestive system propel food through the process. Total time from entry to exit depends on a wide range of factors, from the size of the dog to the quality of the food. Wet food takes less time to digest than dry kibble. Speaking very broadly, operating at optimum efficiency, a dog can process a can of wet food in as few as four hours, while the same amount of dry food can take eight hours to make the same journey!
