Bulldogs World

Hi all, I'm new to the forum so let me do a quick intro. I've had Bulldogs all my adult life and an currently the proud Mommy of Bronx, a 14 month old male Bully. I lived in South Africa until moving to California almost 3 years ago and Bronx is my first pup I've owned in the States. This is also the first time I'm experiencing such allergy and skin issues in the breed. Apart from an occasional ear infection, my previous Bullies were healthy. Maybe it's a climate thing.. I don't know. 

Anyway, I'm hoping someone can give me some insight to helping me get my Bulldogs skin issues under control. I feel like the more we do, the more issues we have! It's like we are almost constantly at our vet trying to fix something or the other!

We have had Bronx since he was 10 weeks old. We put him on grain free right away. He has always had slightly irritated skin on his front legs and/or muzzle to some extent, coming and going. As a youngster, he had a very sensitive tum, and prone to diarrhea and vomiting. We had 3 really bad times where he had to get vet treatment because it was so bad. He did develop cherry eye at 4 months and had surgery. He started reverse sneezing at around 5 months old. He sometimes had very red eyes and redness between his paws that would come and go. 

I'd treat it using oatmeal shampoo, or neosporin if it looked inflamed. But it's gotten worse as he gets older. He was bitten by another dog about 2 months back and his skin really has been going haywire since. He developed lumps around his face, neck, chest snd legs which formed crusty lesions. The fur literally fell out in small batches on those areas. He had 2 shallow puncture wounds on his neck which we treated with neosporin. Because he was due for his neutering the vet didn't want to treat him for his skin until after that. The vet said it looked like atopic allergies which developed a secondary pyoderma infection. So he was neutered a month ago and his skin has gotten worse. The bumps spread out under his legs and on his back. The fur has become very stiff and hard to the touch. The vet put him on antibiotics for 2 weeks and we got clorohexhadine shampoo and spray for him too. The pyoderma healed up but his skin is still inflamed and pink, mainly around his head, neck, chest and front legs. His paws have become moist and the skin had turned a rust color. We have switched him to a fully raw diet, with veggies too and I supplement with salmon oil and probiotics. He only gets natural venison treats. I've tried apple cider vinegar (bathing and in his water), baking soda, we towel him off after every outside trip, we bath him twice a week with the antiseptic shampoo but we aren't getting anywhere.

Yesterday, I found a hotspot starting in between in face wrinkles and am treating him but I'm desperate for a cure from his skin issues, not just a treatment.  The vet said its most likely allergies to dust, moulds etc. We also live in San Francisco which is foggy and humid most of the time, which I'm sure also doesn't help. The vet is talking about prednisone shots but I really don't want to mess with his immune system. I want to figure out how to help my bully heal more holistically. Do any of you have the same issues and what else could I be doing? 

If really appreciate any advice! It's so painful to watch my poor bully go through this. The vet believes his symptoms are all related to his allergies, including the vomiting he has quite often in the mornings. Thanks all!
