There are several VERY good food brands out there. The top of the line though, is IVD limited ingredient diet...you can get this at basically any veterinary hospital. the reason that they have limited ingredients, is so your dog only gets the best nutrition availabel. this makes it easier to detect alergies, which can be deadly to dogs. There are many different flavors, and i mean different! from kangarro, to duck, and also venison. this is the most nutritionsl for you dog. now, there is also waltham. this is also a wide spread and available. please try either of these! they will make your pet VERY healthy, and live long!
