Hi, I understand your frustration, as I also have a female named Blossom, and she has allergies to chicken, salmon, grains and corn. A lot of bullies are allergic or sensitive to chicken, grains and other fillers. Check the labels on the foods you've tried, and see if chicken is a common demoninater. We changed our guys food 4 times before we found a food that they could both tolerate. Many people on this forum feed their bullies Fromm's, it is rated a 6 star food on the dog food ratings on the home forum, it is a grain free formula, and they have 5 flavours, which are all interchangeable with each other. We chose the Fromm's Beef Frittata, because of Blossoms allergies to chicken and salmon. They have been on this food for 18 months and are both doing really well on it. You can also add natural supplements to Buffs kibble, like plain unsweetened yogurt on her morning kibble, this is a very good source of probiotics which boosts the immune system, and is also good for digestion. We also add apple cider vinegar to thier drinking water, there are many benefits to ACV, such as its a natural anti inflammatory, it kills the bad bacteria in the body, so again boost the immune system which helps with allergies, and it also balances the Ph levels of the blood. You can also add a source of Omegas to the evening kibble, such as salmon oil, cod liver oil, or, coconut oil. These are excellent for the brain, skin and coat. It's really trial and error to find a food that they tolerate. Good luck, I hope you find something that is nutritious, high quality, and that Buff tolerates.
