In brief: Cetirizine

The most effective second generation, minimally sedating antihistamine is Cetirizine (adult dose 10 mg at bedtime).
No antihistamine will allow ad lib dog contact so minimize contact, keep dog out of bedroom, use hepa filter in bedroom. If still symptoms have to consider rehousing dog in another home.
