After switching from other quality brands like Diamond Naturals and Taste of the Wild, the quality of WAG is comparable to the other two brands. The price for WAG compared to Diamond Naturals is about the same if not a little more and as for Taste of the Wild, WAG is much more affordable. My dogs have never had an issue eating dog food and this is no different. They still clean their bowls by the end of the day and everyone is happy. With Diamond Naturals I noticed my dogs were eating a lot of grass which indicates to me that something in it was upsetting their stomach. Now every time we go outside the first thing they do isn't graze on grass anymore! My dogs don't usually have gas even when switching foods so I can't speak for that aspect. Overall good quality for the price and since I have three 30 lb dogs (two puggles, one frenchie), this lasts usually about a month for a 30 lb bag.
