Dog hair allergy: or rather dog dander allergy, when you first got the dog, it was your first exposure, but with prolonged exposure, you became sensitized and your immune system couldn't take it anymore, and you started to have symptoms. First you need to stay away from the dog, don't keep it indoors, flush your nose with saline nasal washes every day in addition to any antihistamine, see an allergist if no good
