Hi Lauren D, Welcome to the DFA forums.
I’m sorry your bulldog is having issues 🙁
If you want to find out if your pup has food issues then DogFoodie is right, if done properly, an elimination diet, is the gold standard for identifying food sensitivities and/or allergies. Your poor baby has been suffering with skin issues for most of his life, it’s time to figure out if food is the problem. BTW, I’ve never heard of allergy injections (immunotherapy) for food allergies.
Has his skin been tested to see if he has ringworm, mites, mange, yeast overgrowth, bacteria, or anything else? Bulldogs are notorious for skin issues and skin issues can be caused by many different things, and as Anonymously has said, the type of skin issues you are describing are rarely caused by food issues.
I strongly recommend a high potency, multi strain probiotic to hopefully strengthen and diversify the microflora in his gut. This could also help strengthen his immune system and help his gut health. I would also give him a prebiotic to feed the probiotics.
We’ll all be hoping the best for you and your bully. Please keep us updated 😉
