I am starting this thread b/c I am curious of how many people noticed color changes in food or treats and dogs not responding well to the food when this happens. In another thread someone mentioned something like this and I agree I don’t like color changes. Now my neighbor just mentioned this about Dr. Gary’s Best breed dog food. She said her dog ate 3 bags of food fine then the 4th bag was lighter in color and her dog got diarrhea really bad. She stopped food and he is fine. Just curious now how many of you experienced this.
