I loved reading this piece. Back in the early 70's when fewer than 500 Bouvier des Flandres dogs were ever sold in the USA, we got our first one. The breeder told us about a guy who bought a Bouvier male pup that was born with only one testicle and the dog had great show presence, otherwise. So, the new owner had a testicle implanted to make up for the one that naturally was missing. During a dog show, the judge was checking out his dog and called over the other judges.
Guess what? That other testicle had finally came down and the judge felt three, count them, three testicles.
The poor dog was disqualified and the owner banned from future shows! Ha! You can't make this stuff up!
That's what these things were actually invented for - so that monorchids or cryptorchids could be shown by dishonest breeders and exhibitors.
This whole psychological thing is just cover -- a "beard", if you will.
