YEAST!

I have a 4 1/2 year old female English Bulldog who is relatively healthy except for a congenital defect (recessed vulva) which gives her recurring UTI infections throughout her life. She has had at least 12 infections which have been cleared up with various antibiotics. I give her daily cranberry powder, greek yogurt, and coconut oil which seems to help somewhat. Lately, she has a reddish brown sercretions from her eyes, tail pocket area, vulva area and in between her paws. Around the same time she has a patch under her neck with no fur and red skin.

The vet put her on an anti fungal which is not really working. I feed her twice a day wet and dry food. The dry food (which she has been on for at least 3 years) is Natural Balance Grain Free Sweet Potato and Fish and the wet food is Nature's Variety Instinct Lamb (I switched from Canidae Lamb and Rice because the local stores no longer carry it). Turkey, Chicken, Venison, and Duck don't agree with her so Lamb and Salmon seems to be the best. I have tried the raw diet with her and that completely does not agree with her. I feel like she has a systemic yeast infection and don't know how to fix this. I was thinking about putting her on a cooked diet of Lamb and Vegetables but I don't know if that will help. Also, I know a lot of the posts recommend baths but she is allergic to all soaps and becomes very red and itchy and rips her skin scratching. Usually, I just soak her in epsom salts and that works well.. Any suggestions or experiences about what this could be from? Is it from the anit biotics or food. She really seems ot be suffering and licking herself constantly so I really would like to try to heal this! Also, has anyone had succes with making their own dog food?  Cooked not raw, as mentioned previously raw doesn't agree with her.  She just finished three weeks of anti fungal which did not change this condition.
