Allergies?

After Sams run in with the sheep a couple weeks ago, we decided to do some allergy testing. After we started thinking about it, we started to think allergies were a real possibility. Sam usually has a runny nose. It clears up for a week or two and then its back. We always seem to be around someone thats sick so we didn't think much of it until now. We went to the doctor this morning and did a basic scratch test. They looked at 19 different things--dogs, cats, dust, spores, pollen etc. It was all negative. Not even a hint of anything. In a way thats great news, but it doesn't explain his persistent runny nose. To test specifically for sheep, lanolin or the hay, we would have to do a blood test. The doctor told us to hold off on the blood test since its not very often Sam is around sheep and he really has never reacted to anything else. He just told us to keep track of any symptoms. If we see any pattern or if anything gets worse we can do another test at a later date. So we know he is not allergic to our animals. We don't know why his nose is always running. We do know we wont be taking him to the farm any time soon.
