Will mixed feeding cause upset stomach's in dogs?

The majority of dogs will tolerate mixed feeding very well. Dogs have evolved as scavengers and have a digestive system that is able to cope with a wide variety of different foods at the same time. 

Some dogs might struggle with an immediate switch from processed pet food to raw food, due to the different composition being a shock to their system – and those dogs often cope much better when the raw food is introduced gradually, by mixing it with their previous food. 

There are a small number of dogs who don’t do so well with mixed feeding – and they may need their raw and dry, or wet, food fed at separate times. If you find that it’s not suiting your individual dog to have the two types of food together, try feeding them at separate meals.
