I recently bought 3 bags of CMF 24-20 to feed to my hounds, like I have previously, but as I started to feed to my dogs food has a real strong odor. Dogs ate the food the first feeding but some has issues with loose stools and now on the second feeding most of the dogs will not eat the food. Has anyone else had issues with this food recently? I fed this to my hounds all last season and during the winter with no problems.
