I was just wondering, are there any particular food brands or food dyes that Boxers are commonly allergic to? Our 11-month old just had an allergic reaction to something, and we aren't positive what it was. He was covered in itchy bumps for nearly three days, and we gave him Benadryl, which helped keep things under control. I think it may be because he ate some of my shepherd mix's Moist and Meaty dog food, which has pieces that are dyed red. Are boxers prone to this kind of reaction to certain foods and dyes? I'd just like to know so we can avoid this kind of reaction in the future.
