Dogs are what they eat too!

      
The point is, many of us have been conditioned to feed our dogs the same food, day in and day out. We are warned by food manufacturers and veterinarians alike that it is pointless and even possibly dangerous somehow to change a dog’s food. But a dog who eats the same diet every day can eventually become the living embodiment of the nutritional levels ever-present in his diet. To prevent nutrient toxicity, deficiency, or imbalance, the simple solution is to feed a variety of high-quality foods. 

Smart Switching
There are other reasons to change a dog’s food every few months or so. Switching from one source of protein to another occasionally can help prevent the development of food allergies or intolerances. It can also help prevent a dog from developing a stubborn preference for just one kind of food, which can be very inconvenient.
