Testicles, often referred to as balls, play a crucial role in the reproductive system of male dogs and other mammals. But have you ever wondered when and why these testicles “drop”? In this article, we will explore the journey of a male dog’s testicles and shed light on the importance of this process.
Before the Descent: Where Are They?
When a male puppy is born, his testicles are actually located inside his body, near the kidneys. However, for optimal sperm production, the testicles need to be in a cooler environment outside the body. This is why they gradually descend into the scrotum, a process known as “dropping.” It is worth noting that when testicles remain inside the body, a condition called cryptorchidism, it can increase the risk of certain cancers as well.

The Descent Begins: When Should They Drop?
Around two weeks after birth, the testicles start their descent into the scrotum through a narrow channel called the “inguinal canal.” During the puppy’s health check and vaccinations, veterinarians and registered veterinary nurses often examine this area to ensure the testicles are in the right place.

While the descent of testicles can take a bit longer in some dogs, if both testicles haven’t dropped by around 6-8 months old, they may never do so. In such cases, the next step is usually surgery to locate and retrieve the missing testicle(s).
Contrary to popular belief, testicles actually drop into the scrotum long before puberty in dogs, as in many other mammals. The apparent “descent” during adolescence is attributed to the rapid growth and increased weight of the testicles, causing them to hang lower.
Sexual Maturity: What Happens Next?
Some dog owners prefer to have their dogs neutered once their testicles have descended. The decision to neuter is often based on the estimated age at which the dog will reach sexual maturity. However, it is important to consider that sexual and skeletal maturity can vary among dogs, especially depending on their breed. Small breeds tend to mature faster, while large and giant breeds continue to grow for up to 1.5-2 years.

Veterinarians typically advise waiting for dogs to reach full maturity before proceeding with neutering. Exposure to reproductive hormones during this stage is necessary for the healthy development of their muscular and skeletal systems.
Undesirable Behavior: Why Neuter?
One common reason for neutering male dogs is to prevent undesirable sexual behavior. At sexual maturity, male dogs may exhibit humping and other hormonal-related behaviors that can affect their training. A study conducted in the UK found that 19% of male dogs were neutered because they had already started showing sexual behavior, while 21% were neutered to prevent such behavior in the future. If you are facing challenges during this teenage phase, seeking help from a positive behaviorist alongside your veterinary team is highly recommended.
Potential Complications: What Can Go Wrong?
While the ideal scenario is for testicles to descend successfully into the scrotum without complications, sometimes things don’t go as planned. In some cases, the testicles may not even begin their descent and remain inside the abdomen. Alternatively, they may start but fail to reach the scrotum due to various reasons. This situation can involve one or both testicles. If this occurs, your veterinary team will guide you on the best course of action, which may involve surgery to locate and retrieve the missing testicles. Inguinal areas are also checked, as the testicles may sometimes be found there and necessitate removal.
In Conclusion
Generally, the physical age at which testicles descend in male dogs is usually before they are around 8 weeks old. However, the age at which they start displaying sexual behavior can vary greatly among dogs. If your dog is missing one or both testicles by 6-8 months, it is crucial to discuss the situation with your veterinary team and determine the appropriate time to address the issue.
