I think that I am in fact allergic to dogs.... explains the sneezing ever since I moved into this house(there were 3 long haired shedding dogs here); they are gone now. Since the heat is on and drying up the dog hairs that have gotten into the vents my sneezing has reduced but when ever my housemate brings her pugs downstairs my sneezing starts up and I sneeze at work(Petsmart) a lot. I dont have issues with non shedding dogs though as their hair doesnt get everywhere. Sad but at least its no my kitties, rats, or ferrets. :)
