Diamond Premium Review: Inadequate meat content, by-products, low quality grains and other controversial filler. The first ingredient is by-products. The next two ingredients are low quality grains. Wheat flour is a grain fragment. The use of wheat is a significant negative: wheat is believed to be the number one cause of allergy problems in dog food. Corn is a problematic grain that is difficult for dogs to digest and thought to be the cause of a great many allergy and yeast infection problems. We prefer not to see this used in dog food, yet it is the primary grain in this food. It is a concern to see a fat as the fourth ingredient. Research at Purdue University has identified fat in the top four ingredients of a dry food as a factor that increases the risk of bloat in large breed dogs. Smaller breeds are untested. Brewers rice is a low quality grain and by-product. Beet pulp is further filler and a by-product, being dried residue from sugar beets which has been cleaned and extracted in the process of manufacturing sugar. It is a controversial ingredient in dog food, claimed by some manufacturers to be a good source of fibre, and derided by others as an ingredient added to slow down the transition of rancid animal fats and causing stress to kidney and liver, and commonly causes allergies and ear infections. Fish meal, 7th on the ingredient list, is the sole quality named meat meal ingredient in the food. This is too low to make up an appreciable portion of the food. The above review from the www.dogfoodanalysis.com website rated this food 1 out of 6 stars. (please go to this site to read and make a good choice) Some of the 5 and 6 star rated foods from above site: Nature's Variety, Orijen, Solid Gold, Timberwolf, Artemis, California Natural, Canidae, Chicken Soup for the Dog Lover's Soul, Evangers, Fromms, Go Natural, Innova, Merrick, Natures logic, Wellness, Some of the 4 star rated food: Blue Buffalo, Dr's Foster & Smith, Natural Balance, Performatrin Ultra, Pinnacle, Premium Edge, Sensible Choice Some of the foods above are priced very reasonably (Canidae at my local store is only $32 for 40# bag) The above foods have more calories per cup of food than the cheaper grain based foods. Usually about 450 quality cal/cup versus 350 low nutritional cal/cup. Therfore less food is needed to maintain weight, this offsets the small added cost of the above 22 listed premium brands. Good luck on your choice.
