Particularly low grade, highly contentious or excessively vague ingredient we usually recommend avoiding
Wheat in dog food
Wheat is a common staple in many lower-grade dry dog foods as it is inexpensive and is ideal for forming biscuits and kibbles. It is, however, regularly linked with dietary intolerance in dogs which makes it a highly controversial ingredient.
In wheat intolerant dogs (also called celiacs), the gluten protein contained in the grain damages the lining of the small intestine and prevents it from absorbing parts of food that are important for staying healthy. Wheat intolerance can therefore lead to wide-ranging health problems most commonly affecting the skin, coat and digestive system.
