As others have stated, cryptorchid dogs are at a higher risk of testicular cancer.

Testicular torsion is also a risk in cryptorchid dogs.

My vet said that my pet is cryptorchid. What is that, and will the surgery be different from a "normal" neuter?
Cryptorchid is a medical term meaning literally "hidden testes" (crypt = hidden, orchid refers to the testicle, or testes). This is considered a birth defect - where the testicle doesn't "migrate" out of the body cavity and into the scrotum like normal during fetal development. Some pets can be "late bloomers" and a testicle not present at birth can descend later, but by 4-6 months of age, if it isn't there, it won't likely be. It is a heritable trait, so any pets in a breeding program with this condition should be neutered to not pass on this trait.
Where is the testicle?
That depends! It can be deep inside the abdomen, similar to where the ovary would be found - by the kidney. It may be anywhere from the kidney area to the bladder. It could also be in the inguinal canal, the passageway from the abdomen to the scrotum.
Testicles in the abdomen are not likely to be palpated, but the vet has a good chance of palpating a testicle in the inguinal canal. I say "not likely" to be palpated, because 99.9% of the time, the hidden testicle is much smaller than normal, even when in the inguinal canal. The other 0.01% is for the case that stands out in my mind regarding a cryptorchid dog. He was a geriatric Irish Setter that had been neutered as a pup. Sad thing was, the vet that had done the surgery all those years ago only removed the testicle in the scrotum! This dog was presented for difficulty defecating and urinating, with a large abdominal mass. A very large (12" diameter) testicle was taking over the abdomen! Thankfully, surgery went well, and he could live out his senior years comfortably.
Moral of the story: cryptorchid dogs should NOT be bred, and must be neutered - since the risk of testicular cancer in an abdominally cryptorchid dog is high.
As others have stated, cryptorchid dogs are at a higher risk of testicular cancer.

Cryptorchid testes have a 6- to 13-fold greater risk for developing a Sertoli cell tumor (testicular cancer) compared to normal testes.
Sertoli cell tumor: Sertoli cells are located on the walls of the seminiferous tubules within the testicles and support the development of the spermatozoa. Tumors that originate from the Sertoli cells occur with less frequency in normal descended testicles, but have the highest incidence for occurrence in cryptorchid testes. These tumor cells have a high incidence for metastasis (spreading to other parts of the body). Sertoli tumors present as a firm nodule on the testis, and may reach significant size prior to diagnosis in an abdominal testis. Often males with Sertoli tumors present other systemic symptoms associated with hyperestrogenism (excess production of estrogen) which include anemia, hair loss, feminization, and attraction of other male dogs.
Testicular torsion is also a risk in cryptorchid dogs.

Testicular Torsion
Cause: Testicular torsion, a twisting of the testis around on its venous vasculature, is more common in cryptorchid males with a retained abdominal testis but may also occur in normal males with bilateral testes. Twisting of the venous vessels inhibits blood entering the testis from leaving. As a result, the testis becomes engorged with blood.
Symptoms: Dogs with testicular torsion exhibit pronounced enlargement of the testis. Pain may be so intense as to elicit a state of shock (rapid heartbeat [tachycardia], delayed capillary refill time, pale or muddy mucus membranes, weak pulse, vomiting). Torsion of a retained testis presents as abdominal pain.
Diagnosis: Torsion of a scrotal testis is made upon observation of the acute presenting symptoms and evidence of a firm mass in the scrotum. Torsion of abdominal testis is highly suspect in symptomatic, cryptorchid dogs when abdominal palpation indicates a large, firm mass in the abdomen. Ultrasound imaging is a method for confirmation of this diagnosis.
Treatment and Prognosis: Castration is the preferred method of treatment, particularly in cryptorchid males. Treatment of males with reproductive value is limited to removal of the torsed testis while attempting to spare the remaining healthy testis. Attempts to save the torsed testis by derotation are typically unsuccessful due to irreparable damage resulting from the compromised vasculature.
