Why a Neutered Dog Still Has Testicles
When a dog is neutered but still has testicles, the most common cause is a condition called retained testicles, also known as cryptorchidism. In this condition, one or both testicles fail to descend into the scrotum during development and remain hidden in the abdomen or inguinal canal. According to veterinary data, cryptorchidism is one of the most common congenital reproductive issues in male dogs, especially in small breeds like Chihuahuas, Yorkshire Terriers, and Pomeranians. Because the retained testicle is often internal, owners may not notice it until after neutering, when the scrotum appears empty or unchanged. The American Kennel Club lists retained testicles as a disqualifying fault in breed standards, and many vets recommend surgical removal to prevent future health risks.

Another reason a dog may appear to still have testicles after neutering is incomplete removal of testicular tissue, a condition sometimes called a retained testis remnant. If the surgeon cannot locate the descended testicle during the procedure, or if the dog has a non palpable internal testicle, partial removal can leave behind functional tissue. This can cause continued hormone production, swelling, or a noticeable lump in the scrotum or groin area. Veterinary imaging such as ultrasound or MRI is often used to locate retained tissue, and a second surgery is typically recommended. According to recent veterinary cost surveys, the average cost for cryptorchid neuter surgery in the United States ranges from 500 to 2000 dollars, depending on the complexity and whether abdominal exploration is required.

Health Risks and Treatment Options
Retained testicles carry serious health risks, including a significantly higher chance of developing testicular cancer compared to normally descended testicles. Studies show that dogs with cryptorchidism have an elevated risk of Sertoli cell tumors and seminomas, and the risk increases the longer the testicle remains undescended. Inguinal hernias and testicular torsion are also possible complications that can become emergency situations requiring immediate surgery. Vets generally recommend removing the retained testicle as soon as possible, often at the same time as the initial neuter or during a follow up procedure. The World Small Animal Veterinary Association provides guidelines on reproductive surgery and tumor prevention in dogs https://www.wsava.org/guidelines.
Treatment typically involves abdominal or inguinal exploration surgery to locate and remove the retained testicle. For abdominal testicles, laparoscopic techniques are increasingly used at specialty veterinary hospitals, which can reduce recovery time and complications. Post operative care includes pain management, restricted activity, and monitoring the incision site for signs of infection or swelling. In cases where cancer is suspected, the tissue is sent for histopathology to determine the tumor type and prognosis. According to veterinary oncology data, the five year survival rate for dogs with benign Sertoli cell tumors is high after complete removal, while malignant seminomas have a more guarded outlook depending on metastasis.
