We are going to breed our mare Dixie this spring for the second time. The stallion is a Morgan and he has never been offered to the public because he is only 3. The owner of the stud is requesting a coggins test. I've talked to a few people around here with some top performance stallions, and they think its crazy to ask for this. I'm unfamiliar with a coggins test as I never cross the boarder with my horses. Any information and/or thoughts on this would be a big help.
