Understanding Cryptorchidism in Dogs
Cryptorchidism, also known as retained testicles in dogs, is a condition where one or both testicles fail to descend into the scrotal sac of male dogs. Normally, testicles descend into the scrotum between 6 and 16 weeks of age. However, in cryptorchidism, this descent does not occur.
Definition and Causes
Cryptorchidism is a genetic condition linked to the X chromosome. Breeds that are more likely to carry the cryptorchidism gene include Yorkshire Terriers, Pomeranians, French Poodles, Siberian Huskies, and many others. In some cases, the condition can be inherited by offspring.
Incidence and Inheritance
The incidence of cryptorchidism varies, ranging from less than 1 percent to 10 percent (Whole Dog Journal). Certain breeds are commonly affected, including Standard Poodles, Boxers, German Shepherds, and many toy breeds (Whole Dog Journal).
It’s important to note that retained testicles can be smaller than scrotal testicles, and abdominally retained testicles are smaller than inguinally retained testicles. The right testicle is retained more often than the left due to its more forward-starting position in the abdomen. While late descent of one or both testicles can occur, the likelihood of descent decreases after six months of age.
Understanding the definition, causes, and incidence of cryptorchidism is crucial for dog owners to recognize the condition and seek appropriate veterinary care. In the following sections, we will explore the health risks, diagnosis, treatment options, and preventive measures associated with cryptorchidism in dogs.

Health Risks and Complications
When it comes to retained testicles in dogs, there are several health risks and complications that pet owners should be aware of. Two significant concerns associated with this condition are testicular torsion and cancer, as well as sterility and fertility issues.
Testicular Torsion and Cancer
Dogs with retained testicles are at a much higher risk of developing testicular torsion and cancer compared to dogs with fully descended testicles. Testicular torsion occurs when the retained testicle twists on its own blood supply, leading to severe pain and potentially requiring emergency surgery to correct the condition. Additionally, cancer of the testicles is the second most commonly reported cancer in dogs overall, and it is approximately 12 times more common in dogs with retained testicles compared to those with fully descended testicles. The risk of developing testicular cancer is estimated to be at least ten times greater in dogs with cryptorchidism than in normal dogs. The most common types of testicular tumors seen in dogs with cryptorchidism include Sertoli cell tumors, interstitial cell tumors, and seminomas.
Sterility and Fertility Issues
Dogs with retained testicles are almost always sterile. The undescended testicles remain in the abdomen, where the temperature is too high for sperm to survive, resulting in reduced or absent fertility. While fertility may or may not be affected, it is generally not recommended to breed dogs with cryptorchidism due to the increased risk of passing on this condition to offspring. It’s important to note that even if fertility is not compromised, the risk of developing testicular cancer later in life increases by about 13 percent for dogs with cryptorchidism, making it a significant concern (Whole Dog Journal).
Understanding the potential health risks and complications associated with retained testicles in dogs is crucial for pet owners. Regular veterinary check-ups and early detection can help in diagnosing and addressing this condition promptly. By taking preventive measures and following the advice of your veterinarian, you can ensure the well-being and reproductive health of your furry companion.
Diagnosis and Symptoms
When it comes to retained testicles in dogs, early diagnosis is essential for proper management and treatment. Detecting this condition and recognizing the associated symptoms is crucial for the well-being of your furry companion.
Detecting Retained Testicles
During a puppy’s first examination between six and eight weeks of age, a veterinarian can determine if there are any concerns regarding the testicles. Symptoms of retained testicles in dogs include having only one testicle or none at all (Wagwalking). This condition, known as cryptorchidism, occurs when one or both testicles fail to descend into the scrotum as expected.
In some cases, the testicles may drop down at a later age, making it important to monitor their development as your puppy grows. If you suspect that your dog may have retained testicles, it is crucial to consult with a veterinarian for a thorough examination. Early detection is key in addressing any potential complications that may arise from the condition.
Common Signs and Manifestations
Apart from the absence of one or both testicles, other signs and manifestations may indicate the presence of retained testicles in dogs. These signs may vary depending on the individual dog and the severity of the condition. Some common indications include:
- Inguinal or abdominal swelling: In some cases, the undescended testicles may cause swelling in the inguinal area (groin) or the abdomen.
- Behavioral and temperament changes: Dogs with retained testicles may exhibit behavioral changes, such as increased aggression or territorial behavior.
- Increased risk of testicular torsion and cancer: Dogs with retained testicles are at a higher risk of developing testicular torsion, a painful condition where the testicle twists upon itself. They are also more prone to testicular cancer.
It is important to note that certain dog breeds are more susceptible to retained testicles, although the condition can occur in any breed. Early veterinary check-ups between six and eight weeks of age can help detect any issues early on. Additionally, if there was confusion about the dog’s gender due to bilateral cryptorchidism, the condition may go unnoticed until a later age (Wagwalking).
If you suspect that your dog may have retained testicles or notice any abnormal signs, it is crucial to consult with a veterinarian for a comprehensive examination. Prompt diagnosis and appropriate treatment can help prevent potential health risks and ensure the overall well-being of your beloved pet.

Treatment Options for Cryptorchidism
When it comes to treating cryptorchidism in dogs, the only recommended course of action is surgical neutering. This procedure involves locating and removing the retained testicles from either the inguinal canal or the abdomen. The surgical neutering procedure is crucial for several reasons, including preventing breeding, avoiding complications like testicular torsion and testicular cancer, and eliminating hormonally driven behaviors (PetMD).
Surgical Neutering Procedure
The surgical neutering procedure for dogs with cryptorchidism depends on the location of the retained testicles. If only one testicle is retained, two incisions are made, one for the extraction of each testicle. If both testicles are located in the inguinal canal, two incisions will also be made. However, if both testicles are found in the abdomen, a single abdominal incision will allow access to both.
Immediate removal of the retained testicle(s) is essential to prevent complications such as testicular torsion, a painful condition where the testicle twists upon itself, inhibiting blood flow (Whole Dog Journal). Neutering dogs with cryptorchidism also eliminates the risk of them impregnating intact females and reduces the likelihood of other congenital problems associated with the condition.
Cost Considerations and Prognosis
The cost of the surgical neutering procedure for cryptorchidism can vary depending on factors such as the location of the retained testicles and the specific veterinary clinic. It’s important to consult with your veterinarian to determine the exact cost for your dog’s case.
In terms of prognosis, surgical neutering is highly effective in treating cryptorchidism. By removing the retained testicles, you prevent the potential health risks and complications associated with this condition. Neutering male dogs with cryptorchidism between six to 12 months of age is typically recommended to prevent the condition from being passed down to offspring and to eliminate any negative traits. However, in certain cases where accidental breeding can be prevented, neutering at four or five years old may be considered as an option.
If you suspect that your dog may have cryptorchidism, it’s important to consult with your veterinarian for a proper diagnosis and to discuss the best course of action. Early detection and appropriate treatment can help ensure the health and well-being of your furry companion.
Preventive Measures and Recommendations
Taking preventive measures and following certain recommendations can help in the early detection and management of cryptorchidism in dogs. By being proactive, dog owners can ensure the overall health and well-being of their furry companions.
Early Detection and Veterinary Check-ups
Early detection of retained testicles is crucial for effective management. It is recommended to take your puppy to the veterinarian for the first check-up between six and eight weeks of age to detect any issues early on. During this visit, the veterinarian will conduct a thorough examination to determine if both testicles have descended into the scrotum. If only one testicle is present or none at all, it may indicate the presence of cryptorchidism (Wagwalking).
In some cases, the condition may go unnoticed until a later age if the dog was not checked by a veterinarian early on or if there was confusion about the dog’s gender due to bilateral cryptorchidism. Therefore, regular veterinary check-ups are essential for detecting and managing cryptorchidism, as well as for maintaining overall canine health.
Breeds at Higher Risk and Genetic Factors
While cryptorchidism can occur in any breed, certain breeds are more prone to this condition. It is important for dog owners to be aware of the breeds that are commonly affected. Breeds such as Yorkshire Terriers, Pomeranians, French Poodles, Siberian Huskies, and many toy breeds have a higher likelihood of carrying the cryptorchidism gene. However, it is important to note that cryptorchidism can occur in any breed, and even mixed breed dogs are not exempt from this condition.
Since cryptorchidism is genetic and linked to the X chromosome, it can be passed down to offspring. If a male dog has cryptorchidism, it is advisable to avoid breeding them to prevent the transmission of this condition to future generations. Responsible breeding practices can help reduce the incidence of cryptorchidism in dogs and promote the overall health of the breed.
By staying vigilant and seeking regular veterinary care, dog owners can play a proactive role in the early detection, management, and prevention of cryptorchidism. Timely intervention and appropriate treatment can help mitigate the health risks associated with this condition and ensure the well-being of their canine companions.
