I think that he is marking and at his age it can be almost impossible to stop. I think the best chance is to get him neutered, but at his age it might be too late already.
Marking is an extremly strong instinct and this is going to lead to a very unhappy, frustrated owner and a very scared yorkie. You must likely will have to use belly bands at all times especially if you breed him. Most stud dog do have to wear them at all times due to their constant marking. I would seriously perhaps think if you can not stop with the rubbing of his nose in it, or using negative punishments that maybe you should think to rehome him. All the best. |
