The dog is still in my ownership but your system won't list him at stud?

The bred here section is for dogs that you have bred but no longer own. Such dogs can only be advertised at stud by their registered owner and appear on the account of the person they reside with.

If you own the dog and he resides with you, then you need to remove him from the bred here section. If the dog does not reside with you but is held in joint ownership, then he must appear on the account of the person he does reside with.
