My puppy has an undescended testicle. When is it safe to neuter him?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | unneutered | 9 months and 26 days old | 125 lbs

Have a Daniff puppy 11 months old and 125lbs who has one testicle that has not dropped. Concerned about neutering to early risking healthy growth but equally concerned about cancer risks surrounding the testicle that has not dropped. When should I have him neutered?

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.
