Walk down the dog food aisle, or scroll an Amazon search for "hip and joint supplement," and you will hit a wall of bags and bottles that all claim to be the best choice for your dog. Grain free, limited ingredient, high protein, senior formula, salmon oil, glucosamine and chondroitin. The labels all sound confident. Few of them tell you what is actually in the bag or bottle, how it compares to the rest of the shelf, or whether other dog owners kept buying it after the first order. Petof exists to make that comparison for you. Our research team reads the guaranteed analysis, ingredient list, form and flavor on every product we cover, then lines it up against life stage, breed size, price per pound or per dose, and how many owners are actually buying and rating it. A supplement with a compelling label but almost no reviews gets ranked lower than a plain-looking one that thousands of owners keep reordering. We are not paid to feature any brand, and our rankings move when the underlying data does. Right now that covers dry, canned, freeze-dried, dehydrated and veterinary diet dog food, toppers and pouches, and health categories including probiotics, hip and joint care, fish oil, skin and itch relief, ear and eye care, calming aids, dental care, dewormers, herbal supplements, multivitamins, antioxidants, and recovery gear. None of this is veterinary advice. For an ongoing health issue, a vet who has examined your dog is always the right call. Questions about a page or a correction to a spec: [email protected].
