Can dogs digest different foods at the same time?

Of course kibble and wet food, or kibble and raw food are very different and you might see someone saying that this means they can’t be fed together. Raw food contains high levels of protein and moisture, while kibble contains high levels of carbohydrate and very little moisture. This means that some people believe that they digest at different rates, or that they require different levels of stomach acid (pH). 

Digestion is very sophisticated and is able to easily cope with a variety of different foods. Your dog will produce the required enzymes, and stomach acid, based on the types and amount of protein, carbohydrates, and fats that are eaten, regardless of whether those came from raw food, or processed food, or a mixture of both.
