BLU is my baby but he has a serious medial condition:

Having one descended testicle, called cryptorchidism, is considered a genetic defect and is, indeed, a family trait. Finding only one testicle during an exam does not mean the dog has only one testicle. In most circumstances, there are two--one you can feel in the scrotum and one tucked up into the abdomen where it developed when the puppy was still an embryo.
In developmentally normal male dogs, the testes descend fully into the scrotum before they are 2 months old. Sometimes, both don’t make it out of the abdomen and into the scrotum. One may make it part of the way, or it may not budge at all. If a testes makes it only part of the way, it can usually found hiding out along the “bikini line” . For the ones that don’t budge, we need to surgically remove them at the time at the neuter to reduce the increased chances of the retained testicle becoming cancerous. This type of surgery is more invasive (involves entering the abdomen) and expensive than a normal neuter. So the recommendation for a reputable breeding program is to include intact (two descended testes) males only.

My docter here in town told me that this is a very iffy procedure and he may not make it at all... Blu is my life and I love him more then any living thing in the world... Please do what you can, send any information you can... and if you know a doctor who is willing to do this procedure, please send a message asap.
If left in the body, that testicle may cause an specific kind of tumor, described as tumor cellular sertoli, which is malign.
