'''Background:''' Gluten is present in various grains such as wheat, rye or spelt and may cause coeliac disease in humans, which is an auto-immune disease with a prevalence of less than 1%<ref name="Gujral">Gujral, N., Freeman, H. J. and Thomson, A. B. (2012) '''Celiac disease: prevalence, diagnosis, pathogenesis and treatment.''' World J Gastroenterol 18(42):6036-59.</ref>. Nevertheless, some people do increasingly avoid products containing wheat. The increased demand for gluten-free products in human nutrition even led to instances where products naturally free from gluten were marketed at higher price as being gluten-free. This demand and owner expectation has also extended to pet food although gluten-intolerance strictly speaking does not exist in cats and dogs.

A special case, known as gluten enteropathy, is found in the Irish setter, where a rare hereditary disease affected certain lines of Irish Setters in the past. After weaning puppies showed diarrhoea, small intestinal pathology, wasting and delayed growth. The symptoms settled and puppies grew normally when wheat gluten was removed from the diet. Many pet owners, therefore, still deem wheat gluten as being unhealthy although the disease is no longer prevalent and is also uncommon in other breeds. For the majority of dogs, it is not clear what benefits a gluten free diet really brings.
