My 7-month-old male puppy has only one testicle. Is this normal?

Dogs have two testicles. Soon after they are born they descend from the abdomen into the scrotum. If only one has descended then the other testicle is retained in the abdomen. This testicle should be surgically removed since the retained testicle can develop cancer more often than the normal testicle. Usually when he’s neutered they will remove the one in the scrotum and open him up like spaying a female to remove the other one. This can be a genetic problem so I do not recommend breeding him.

If the testicle is just under the skin on his belly he could have an undescended testicle. In puppies this can sometimes correct with age, but if he is 6 months or older it likely won’t drop anymore. The vet can surgically remove the testicle during a neuter surgery.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. This condition is known as cryptorchidism and it is not recommended to breed these dogs due to the potential for passing on this condition to the offspring. The undescended testicle should be removed during the neuter procedure. Once neutered there are no concerns. I hope this helps! Please let me know if you have any further questions or concerns and I would be more than happy to help you further.

I am afraid it is unlikely they will descend at this stage. Cryptorchidism in Dogs, or retained testicles is a condition which needs to be surgically treated. The testes normally descend into the scrotum while an animal is very young. For dogs the descent to the final scrotal position is expected to be complete by the time the puppy is two months old. It may occur later in some breeds, but rarely after the age of six months. I would suggest scheduleing an appointment with a different veterinarian to have Beerus examined and to make a treatment plan.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! You should be able to feel the testicles. If you only feel one then the other testicle is still not descended. They should be both down by birth or by 4 months. It just means the vet will have to search for the retained testicle when he gets neutered. He should be neutered because it is a congenital or genetic disease and the testicle can become cancerous over time. I hope this helps!

If you have had Czar since he was a puppy and know that he was not neutered, then he is considered cryptorchid. This is a concern because testicles that are in the abdomen (not in the scrotum like they are supposed to be) are prone to becoming cancerous. I would recommend scheduling an appointment with your vet to discuss neutering him before he develops any problems. I have included more information on cryptorchidism below. https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=2743 I hope that was helpful! Thanks for using PetCoach.

Oso is very cute! By six months of age, both testicles should be descended into the scrotum. If they are not by six months of age, then it is unlikely that the other testicle will fall into place. This testicle has the potential to turn into a specific type of tumor and so you will want to make sure to have him neutered. Hopefully it will come down on its own! Best of luck and please feel free to post any additional questions.
