Hi Minah, and welcome to EBN. I'm so glad you found us. Fat Louie is absolutely adorable, I love his outfit, so cute. Wow you sound very busy, and a lot going on. Congratulations on going to school, I'm planning on going back to school in Sept. and know how difficult and challenging that can be, especially when you have a family, and household to run, I'm sorry you're going through Chemo, and hope treatment is going well, and your okay. Sending love and prayers your way.
All the symptoms you describe with Louie are definitely allergy related, and most allergy symptoms that he has, the red paws, the red face, the skin issues, etc are all signs of a food allergy. My female Blossom has allergies to chicken, salmon, corn and grains. We switched our guys food 4 times before we found one that both our guys tolerated. We feed our guys Fromm's Beef Frittata grain free, and they both do really well on this food. Have you read the dog food ratings forum on the home page? It lists and grades all the dog food brands from 6 star and down. When choosing a food, you want to choose a 4 star or better, and you're best to choose a chicken and grain free food, as most bullies are allergic or sensitive to these. Which brand of food are you currently feeding Louie now? We also add 2 Tbsp's of plain unsweetened yogurt to the morning kibble, this is great for digestion, but is also a source of probiotics which help boost the immune system, which helps kill bad bacteria, and helps to fight infections and allergies, we also add 1 Tbsp. of Omega Oils to the evening kibble, you can use salmon oil, cod liver oil, or coconut oil, this is good for the skin, fur, and joints, as well as the brain. We also add 1 Tbsp. of apple cider vinegar to their drinking water everyday, there are a lot of benefits to ACV, it is a natural anti inflammatory, it kills the bad bacteria in the body, so boosts the immune system, and it balances the Ph levels of the blood. It is also very good for the skin and fur as a final rinse after shampooing, it kills lots of bacteria on the skin, and makes the fur so soft, it also helps them to smell nicer longer in between baths. I like using these things because they are all natural, and inexpensive, and can be bought at the grocery store, drugstore, or a health food store. I hope Louie continues to improve, and you find a food that agrees with him, and he tolerates. It can be very frustrating process to find the right food, and it really is just trial and error. Good luck and keep us posted.
