Though it may seem like dog food is dog food, not all dog foods are created equal. The quality of pet food products varies greatly from one manufacturer to another, and you can’t always trust what you see on the label. While there are many high-quality dog food brands on the market, there are also those that cut corners by bulking up their products with low-quality fillers and artificial additives. Pet foods are not regulated to the degree that human foods are, so if you want to find a quality product for your dog, you’ll have to do some digging.
