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.
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.ecause 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.
