I buy the cheap dog food and yes it makes my dogs gassy but at least the food did not appear on the list. I buy the Dad's dry food and the Dad's indoor formula for my cats. This is the only food any of my animals will tolerate. If my regular store doesn't have it I have to go to another store to see if they have it. For me to buy most expensive food isn't worth it. Especially if the fur kids won't eat it.
