I know that a cough in a sheep is a bad thing, but we are new to keeping sheep, and have only had these guys for about three months. Our Icelandic ram (Sue) coughs a dry hacking cough every now and then. My husband hasn't heard it at all, and I've heard it about three times. My daughter sheepsat for us this weekend, and said she heard it twice. There are no vets within 30-40 miles of us that will handle sheep. What should we do, if anything?
