hopefully it was just the antibiotic causing her reaction. or it could have been the rice. rice is a grain. a lot of dogs are allergic to grains. and IMO, starchy carbs like rice and potatoes are completely unnecessary in the diet. if you really want to add veggies in, try an uncooked (cooking removes many of the nutrients you are trying to add) broccoli and carrot paste (you can make it with your blender). They contain most of the nutrients found in veggies. also things like berries (blueberries, raspberries, blackberries) are fine to add on occasion (or you can add a few of them to your broccoli/carrot paste) to keep things balanced if that's what you're concerned about. other than that, you need to stick with strictly meats (which includes both raw meaty bones like the chicken quarters you're feeding, AND organ meat once a week or so). good luck in your quest to find something that works for you!
