Do dogs testicles get bigger with age?

Answered by Frank Schwing

Dogs do experience changes in their testicles as they age, but it is important to note that the growth pattern differs from humans. Unlike humans, who experience a sigmoid growth pattern in their testicles, dogs go through a different process.

During the early stages of a dog’s life, the testicles are not fully developed. They typically descend from the abdominal cavity into the scrotum around 6 to 8 weeks of age. At this point, the testicles are relatively small and continue to grow as the dog matures.

The growth of a dog’s testicles is influenced by various factors, including breed, genetics, and hormone levels. Typically, the testicles reach their maximal growth between 6 to 12 months of age. However, it’s important to note that individual dogs may have variations in their growth patterns.

After the initial growth period, the size of a dog’s testicles tends to stabilize. In most cases, the size of the testicles does not significantly increase with age. However, it’s crucial to monitor for any changes in size, shape, or texture, as these could be indications of underlying health issues such as testicular tumors or infections.

It is essential to keep in mind that the size of a dog’s testicles does not necessarily correlate with their overall health or fertility. Small or large testicles do not inherently indicate any problems unless there are other concerning symptoms present.

If you notice any abnormalities in your dog’s testicles, such as swelling, lumps, or changes in size, it is recommended to consult with a veterinarian. They can perform a thorough examination, conduct necessary tests, and provide appropriate guidance based on your dog’s specific situation.

While dogs do experience changes in their testicles as they age, the growth pattern differs from humans. Testicles in dogs typically reach their maximal growth between 6 to 12 months of age, and their size generally stabilizes afterward. Monitoring for any changes and seeking veterinary advice if abnormalities are detected is crucial for maintaining your dog’s overall health and well-being.
