Should I neuter my dog with a retained testicle? Cancer risk?

Updated On September 23rd, 2025

Pet's info: Dog | English Setter | Male | neutered | 50 lbs

I have recently adopted a 4 year old English Setter. In the past week I have noticed he only has one testicle descended (he was never neutered) and it feels as if the other testicle may be in the side of his inner thigh. Is this advisable to get removed now at his age? Is this surgery common? What signs and symptoms reveal testicular cancer in dogs?

I would definitely get Huxley neutered. He's not too old to be neutered, and given that he has a retained testicle, neutering is highly recommended. The retained testicle is more prone to testicular tumors and testicular torsion. Testicular tumors are more common in older dogs, but warning signs include swelling in the testicle, hair and skin changes, nipple enlargement, and pale gums among other symptoms. I would speak to a vet about scheduling Huxley for a neuter very soon.

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! If Oreo has a retained testicle (hasn't dropped in to scrotum) then it should be removed. The testicle needs to be at a lower temperature than the body. There is a risk for the retained testicle to become cancerous over time. Put your trust in to your Vet and medical professionals. Have a great night

    If Sorn's testicle has not dropped by now, it will not drop. Neutering him at 11 months will not have any adverse effects on his growth, and I would recommend having it done as soon as possible. You are correct that there is a much higher risk of testicular cancers with this retained testicle, but there is also the risk that the testicle can twist on itself, cutting off it's blood supply. I would speak to Sorn's vet about having him neutered.
