Kirkland Signature Lamb, Rice & Vegetable Review

Kirkland Signature Lamb, Rice & Vegetable

Most foods available in supermarkets and warehouse stores rank at the bottom of what pet-food advocates say you should feed your dog. However, those who have a Costco membership do have one relatively high-quality and low-cost option: Kirkland Signature dog foods, including Kirkland Signature Lamb, Rice & Vegetable.

ProsGood meat content, Decent-quality grains, Chelated minerals to help with absorption, Value pricedConsAvailable only at Costco, Part of 2012 recall

Ingredient quality

Meat first, with decent-quality grains. Mike Sagman at gives Kirkland Signature dog foods his second-highest rating, 4 stars, and says its ingredients make it an above-average kibble at a value price. Grains are certainly part of the mix, but they are mostly decent-quality grains like brown rice and barley. Although less-desirable white rice and rice bran are used, lower-quality grains like corn and wheat are not. Meat (lamb and lamb meal in the case of Kirkland Signature Lamb, Rice & Vegetable) leads the ingredient list. Though Kirkland Signature isn't completely free of controversial ingredients, what's there (like brewer's yeast) is on the low end of the concern scale, and minerals are chelated to help absorption. Most other experts that review the food rate it similarly, but is even more impressed, naming Kirkland Signature to the site's list of top dog foods.

Product safety

Recalled in 2012 for risk of salmonella. Kirkland Signature dog foods are made for Costco by Diamond Pet Foods, which also makes several high-quality pet foods that cost much more. However, that means that it was caught up in the same spring 2012 voluntary recall that ensnared Diamond, as well as certain batches of foods from other well-regarded brands, because of concerns over possible salmonella contamination at Diamond's South Carolina plant. Kirkland Signature foods meet Association of American Feed Control Officials (AAFCO) standards for nutrition.


Best budget-priced dog food. Kirkland Signature is a much better choice than most supermarket kibbles, experts say. For the price, you won't find a higher-quality dry dog food. For example, pound for pound Kirkland Signature is similar in cost to Purina Beneful (Est. $14 for a 15.5 lb. bag), but with a far better line up of ingredients. You can get even better quality dog food, of course -- but you'll have to spend more. Taste of the Wild High Prairie is just about the cheapest grain-free kibble, but it costs about twice as much as Kirkland. Super-premium foods like Orijen Adult Dog Food (Est. $80 for a 26.6 pound bag) pamper your pet with human-grade meat, but they're the priciest of all.

Kirkland Super Premium (Lamb), Editors of, Not Dated

Earning a 4-star rating here as well, Kirkland dog foods are called "a pretty high quality product for the amount of dollars that it costs to buy." The biggest knocks are the use of white rice and rice bran and the fact that it's only available at Costco.
