My Petie had both testis at 10 wks, then one moved, we could see it.
In the the JRTCA/JRTCC/JRTGB, Jrts are registered on their own merit at a year of age, instead of being reg'd just because they have reg'd parents.
One of the faults that doesn't allow us to register is an undecended testis.
And if I wanted to compete especially in any National event, he had to be Reg'd. I waited until he was over year old in hopes that it would move to the right spot, didn't happen. By this time, he already had a very nice career and was winning and winning performance championships right, left and center.
I neutered him, for his health first and foremost, to register him and because it was the ethical thing to do.
This dog has gone to win National Championships, be a proven Working Terrier and to basically excell at anything I have ever asked him to do and he has been my best dog.
And I hope that your breeder, if they sold you a dog as a breeding prospect does the right thing and gives you some of your money back to the price of a pet quality puppy.
I know it's hard, I have been there because we want them to be everything that we had dreamed of but...............but imo it should be as a neutered dog.
There is no question that it isn't an inherited problem from the research done and there is no question that it can't cause health problems by the way of cancer from the reseach done. And we have to do right by the future generations just not our own dog, imo.
Good luck
