According to the information I was given by the previous owner, my gelding is 9 years old - he will be 10 in October. However, several people, including a vet and a dentist have aged him at an estimate of around 12 years old. So I did a bit more digging and managed to get hold of his breeder, who confirmed that the original information I was given is correct and that he is 9. He cannot be any older as she only started breeding from the sire in the year before he was foaled. Unfortunately, he has no actual papers. This is not the first time this has happened to me, as a previous mare I owned was aged at 11, 15 and 16 by a vet and two different dentists. When I received her papers she turned out to be 14. From my (limited) experience, it seems a rather inaccurate way of determining a horses age. Has anyone else had a similar experience to this?
