This is happening far too often, the perfect stallion is advertised, you think he will be a perfect cross for you mare. You look up his pedigree and find that he is not in the owners name~!!!!! What is with that!!!
All mare owners should check with the registry that the stallion they want to breed their mare to is in the stallion owners name. It has been happening way to often, a stallion is advertised then a quick check reveils that the wrong name is on the papers. This can lead to huge headaches when you try and register your foal.
You can look up on line, or just call the registry that the horse is registered with and they will be more than happy to help you.
