At least 30 per cent of my clients that report behavioral problems find that a change of food changes the unwanted behavior. No matter what a food company claims unless your dog has bright eyes, silky hair and supple skin, and is not overweight, then the food is not right for him. Not all dogs do well on a particular brand of food, some dogs simply do better than others. Most foods are categorized as Economy, Regular, Premium, Super Premium and Performance. Regular and Premium foods are not formulated like a Super Premium or Performance food.
Dogs have simple stomaches and short digestive tracts for digesting meat.
They also lack the saliva enzyme amylase, which is necessary for pre-digesting starch. Dogs have adapted to foods with high vegetable protein levels, however they perform better when fed foods high in meat protein and animal fats. Checking the label of a Super Premium or Performance food an animal protein will be listed as the first or second major ingredient. These should include either chicken, or turkey meat, or poultry by products meals, meat or pork meals or other animal by products. A least two sources of fat or oil should be included for adequate energy and essential fatty acids.
