Hi, it may very well be allergy related, as my female also had the same reactions, her face would get red or pink, she had warm pink ears, she licked her paws a lot, and she has chin acne, little bumps on her chin. We have discovered through trial and error, and 4 food changes that Blossom is allergic or sensitive to chicken, salmon, grains and corn. Looking at the ingredients, it looks like a good nutritional food, but if Castor is allergic or sensitive like most bullies are to chicken, then the chicken Ingredients in this brand could be causing the symptoms, also another ingredient that can sometimes cause problems is potatoes, and also the oats, oatmeal sometimes causes allergies as well. We switched our two guys to Fromm's Beef Frittata, which is a good quality food listed on the dog food ratings forum and is used by a lot of members on here, it is also a grain free food. My two have been on this food for 12 months now, and are both doing really well, I used to have to give Blossom a Benadryl all the time before we switched, and now she never needs it, and their poops are firm but soft, and they go 2 or 3 times a day. I hope this helps.
