Eczema And Blepharitis Getting Worse - Dog?

I've have vitiligo for years and always had dry skin with occasional eczema spots on my body. I also have pityriasis rosea on my side for years which finally cleared with antifungals.

Last summer I started to get blepharitis under my eyes but I thought it was just a one-off or due to a couple stressful events in my life.

The blepharitis did start a few weeks after I started visiting a dog at a pet store in short 20 min intervals a couple times a week until finally purchasing her. I never noticed I had any allergic reaction to the dog when I'm in her presence. No sneezing, runny nose, watery eyes, itchy skin, etc.

I later purchased the pup and my blepharitis continued to get much worse and it eventually spread to other parts of my face and my entire body started getting more eczema spots. It then became very widespread.

I am able to control the symptoms with steroids and Elidel but I'm trying to get to the root of it.

I realize it may sound like it's definitely the dog, and it certainly may be, but I don't notice that when I'm interacting with the dog that I'm itchy or anything.

Before I consider giving the dog to family, I want to understand if it's possible it's something else.

If you do believe it's my pup, are there any options besides ridding myself of my dog -- (I already bathe her, vacuum, etc).
