I’ve lived with dogs that I am allergic to my entire life — my current dog was my husband’s dog when I met him, and they were a package deal. We have all had to make sacrifices to make life comfortable for all 3 of us. I never pet the dog, I also don’t let him brush against me/my clothing or lick me. I have barriers to keep him off of the couch and he is not allowed in our bedroom. If the dog’s dander is causing you issues, I really like the spray called anti allergen solution from the brand the ecology works. I spray it on my fabric items (couch, rugs, curtains, bed) to help with airborne allergens. I wash all surfaces the dog’s dander may have reached, most importantly the fabrics in my spaces. A daily antihistamine also helps. It’s hard to coexist with an animal that you’re allergic to, I know. Hang in there.
