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.
Big dogs and small ones digest food at the same rate. The fact is, your dog's digestion times are more likely to be influenced by what you feed him than by his size. Because your small dog eats an amount of food proportionate to his size, his body breaks down food in the same manner as a big dog's would. The time it takes for food to digest in your small dog is essentially the same as in a dog twice his size or larger.
