There are certain things all beings are meant to eat, and for humans it's certainly not chewing on chips for their entire life. Likewise, Dogs have special needs in nutrition and taste.  

Humans have been feeding dogs leftovers for centuries and have now changed the routine by feeding highly processed dry kibbles, all for the sake of convenience.  

Fresh food is the best source of nutrition, which is naturally compatible with their bodies and gives them the right nutrition.  

Nothing beats home style cooked food, literally.
