What food is appropriate will depend on how sensitive your dog's GI tract is to these ingredients. There are some over the counter foods without these ingredients in them. A low cost version available at Tractor Supply is the 4Health Salmon and Potato formula: https://www.tractorsupply.com/tsc/product/4health-salmon-potato-formula-for-adult-dogs-5-lb-bag?cm_vc=-10005 Another option available at most pet stores would be Purina Proplan grain free formula such as the Savor Turkey and Chicken formula https://www.proplan.com/dogs/products/savor-grain-free-adult-shredded-blend-turkey-chicken-formula#ingredientsandguaranteedanalysis However, over the counter foods are made in facilities that produce many different foods so contamination of a food with an ingredient not on the label is a possibility. If the food allergy is severe, then a prescription diet available from your vet may be necessary (these special foods are made in a facility where contamination doesn't occur). These foods are unfortunately much more pricey. Another option is cooking for your dog. You can use the website Balanceit.com to find a properly formulated homemade diet for your dog.
