I just wanted some opinions on some dog foods I am interested in. The first food is Wellness, Natures Variety and Canadaie. One of my concerns is, I was reading on a boxer forum about Citric acid (used to preserve food) can cause bloat when the kibble is watered down. Read this site and go down to the part of preservatives. http://www.boxerworld.com/feeding/ I always water down kibble and add canned food with every meal, I also own 5 dog breeds which are prone to bloat. This concerns me. As far as I can see Wellness only uses mixed tocopherols to preserve their dog foods. But, Natures Variety http://www.naturesvariety.com/ does use citric acid. I am really impressed by the ingredients that natures variety uses and the way they process kibble. Insert from site: Nature's Variety realizes how heat compromises many food components. So several of these heat sensitive food ingredients -- including probiotics, enzymes, nutritious oils and fats, and certain vitamins and minerals -- are dry enrobed back on the outer surface of the finished product through a process called Bio-CoatingTM. All Nature's Variety products are naturally preserved with vitamins and herbal extracts and hermetically sealed in oxygen limiting packaging. The CANIDAE - All Life Stage Benefits does not use citric acid to preserve either. http://www.canidae.com/ I would like to rotate my dogs on these 3 brands of food. I am just concerned about Nature's recipe and the citric acid. Every thing else about this company sounds wonderful. has any one fed Natures variety? what are your thoughts on the ingredients?
