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.
The normal time for a stomach to completely empty dry dog kibble into the intestine is 1-8 hours. For liquids the stomach can empty almost immediately into the intestine. In an abnormal dog's system it can take up to twice that long to empty the stomach. I hope this helps, best wishes. Dr. Dan
