I have heard that allergies changes, some years you might not be allergic and others you might. The reason i know is because i asked the same question in the other forums i belong to. About 5 years ago i had an Affenpincher mixed and you know they have a really rough coat almost like the Scottie tho the Scottie coat is soft compared to my other dog. I could not play with him because each time i would pick him up or touch him i would get little mosquito like bites in my arms and legs. It would itch really bad, so 3 days later i ended up giving him away. I could hardly touch him without getting those little things. His coat use to be the issue his little hairs would pinch me, never got a stuffy nose, or watery eyes. But i do have the issue with cats, never mine which i had for over 3 years before he ran away. Other people's cats. So is really weird. I would suggest visiting an Allergy's Clinic see what they can do for ya.
