Food & NutritionWhat affordable dog food is safe for corn, wheat, soy allergies?
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.
