Also by popular request we've added 'Buy Now' buttons (updated as of January 2010). These buttons link to sites with the lowest prices found for the dog foods and cat foods. Note that many of the veterinary prescription diets require a prescription in order to purchase. Veterinarians are required by law to provide a written prescription upon request, making it possible for you to save money by purchasing for less online (or elsewhere).
Notes on Prices: The prices listed for the dog and cat foods above do not include sales tax (or shipping from online merchants), and may vary from region to region (and from store to store). Prices last updated as of February 10, 2010.
It's important to note that in the last year and a half prices have risen dramatically (ranging from 20% to as much as 70%!), largely due to an increased use of U.S.-only ingredients in the wake of the 2007 Pet Food Recall as well as increased production and shipping expenses. Pet food manufacturers have also frequently resorted to decreasing the size (total weight) of their bags, and in many cases (especially with the veterinary diet dog foods) have significantly increased prices while also decreasing the dog food bag size.
The cost per day figures are for the dry dog foods only and are based on the manufacturers' suggested feeding recommendations for a 50 lb. dog, which are as follows: 2 1/2 cups/day - Purina Canine NF, 3 1/3 cups/day - Iams Renal Early Stage, 4 cups/day - Royal Canin Canine Renal MP 14 , 2 3/4 cups/day - Hill's Prescription Diet u/d, 3 cups/day - Hill's Prescription Diet k/d, 4 1/2 cups/day - Royal Canin Urinary SO 14, 3 2/3 cups/day - Royal Canin Urinary UC 18 Low Purine, 2 cups/day - Flint River Ranch Lamb and Rice, 2 1/8 cups/day - Flint River Ranch Fish and Chips, and 1 3/4 cups/day - Flint River Ranch DryWater Dog Food.
Notes on Ratings: The star ratings for the prescription and premium wellness pet foods are based on four factors: ingredients (well-balanced diet, low/high purine content, added vitamins and minerals, presence – or absence – of unnecessary fillers, artificial additives, and chemical preservatives, etc.), guaranteed analysis (primarily with respect to protein, phosphorous, and sodium content), daily cost to feed, and palatability (a taste and smell combination that's appealing to dogs). Pet food manufacturers are not required to list the level of purines in their pet foods, leaving it up to the consumer to research the purine content in a given pet food.
Dog breeds predisposed to urolithiasis (the clinical term for urinary stone health issues) and similar urinary and kidney issues include the Dalmatian (aka Dalmation), Beagle, Bulldog, Basset Hound, Cocker Spaniel, Bichon Frise, Miniature Schnauzer, Lhasa Apso, Miniature Poodle, Miniature Schnauzer, Yorkshire Terrier, Dachshund, Newfoundland, Irish and Scottish Terrier, and Irish Setter.
IMPORTANT DISCLAIMER: No ratings or claims are made for the efficacy of any of the dog food formulas listed on this page. No pet food can claim to offer a cure for kidney or urinary diseases; however, a nutritious and balanced wellness diet may strengthen the immune system and improve vital organ function (among other health benefits), which may help to prevent and/or manage renal health issues. The information on this page is provided for educational purposes only and is in no way meant to be interpreted as veterinary advice. Nutritional veterinary advice on a specific pet's case cannot be given due to laws regulating veterinary licensing, and any decision to change a pet's diet should be made in consultation with a veterinarian and/or licensed pet nutritionist.
