Again, very simple: whoever first generated the thought to get that breeding done is the one who should be listed as the Breeder.
You would mention the person with whom you collaborated, or who assisted in some way, in The Notes.
You can keep doing what you're doing at the ADBA, but here you need to do things differently.
First of all, the ADBA isn't a digital, cross-referencing database.
Secondly, again, because of this, they don't have to be as tight in their criteria.
In the example of what you gave above, the solution is clear as day: YOU are the breeder. YOU had the original thought of "using someone else's bitch" to get a particular breeding done, and so YOU should be listed as the breeder. If the actual owner of the bitch had the original thought, and wanted to get the breeding done, using his own bitch, then obviously HE would be the breeder.
But, in what you described, YOU wanted to get a particular breeding done, the thought first originated in YOUR head, and "he" just let you use his bitch to get that breeding done.
YOU should be listed as Breeder ... and you can say whatever, "I wish to thank so-and-so for letting me borrow his bitch," that you want to in The Notes
That is the way things need to be done here, thanks.
