Like people, dogs can develop sensitivities to certain ingredients. Dogs tend to do really well digesting most proteins, but sometimes chicken can become problematic. Which is where novel proteins can be beneficial. Other dogs may develop allergies or insensitivities toward grains or carbohydrates, for these dogs, a limited ingredient diet is the perfect solution. Even if your dog does not have any issues, a limited ingredient diet with lots of protein can be incredibly beneficial for their health.
