Hi, I'm not sure how many other members have had allergy issues with beef, I think the majority of allergies are to chicken, but I'm sure there are others who have bullies that are allergic to beef as well. I have just recently had to switch my two guys from Fromm's Beef Frittata to Fromm's Lamb and Lentil. My female Blossom is allergic to chicken, salmon, corn and grains. We switched foods 4 times before we found Fromm's Beef, and they did really well on this food for the past 2 years, until now. For the past month Blossom started showing some signs of allergies again, she's mostly just licking her paws, and itchy, but Dozer who never had any problems with foods or allergies, is also showing allergy symptoms. He's been licking his paws excessively, until they are soggy, he's been getting goopy eyes, he was shedding like crazy, which he never did before, and he smells sour from his ears. I think he may have yeast. I switched them to the Fromm's Lamb, and they both seem to be doing better, and the shedding has stopped. I'm hoping they will tolerate this food, and their symptoms continue to improve. I guess time will tell. I wonder if being on the same food for over two years can cause an intolerance?
