Reducing allergies to dog?

[Me and my fish]

My mom is allergic to my dog (she is 3/4 bichon frise and 1/4 poodle meaning she dosent shed. Both of these breeds are supposed to be really good for allergies. my puppy is 8 weeks old). My mom has watery eyes but no physical changes. Could she be imagining she's allergic because she is so scared of it happening? I've heard of this happening before. She set up an appointment to talk to her doctor and he said she cant have shots because of the high risk. She is allergic to almost every type of antibiotic there is. What can I do to help reduce her allergies? Help!!!
Please help me I refuse to get rid of her!
I love her SOOOOOO much!!!!
