When should I neuter my Dachshund? Will it affect growth or roaming?

Updated On September 23rd, 2025

Pet's info: Dog | Dachshund miniature | Male | unneutered | 5 months and 7 days old

Advice from vet on here, re neutering a Dacshund was: ‘I would do that before he gets the idea of roaming, as this can become a habit and then neutering will not influence this behavior.’ When do I know when this will be? He is 5 months now. My worry continues to be the slowing down of growth if done too early. He and his sister are together so we wouldn’t want her to be on heat with him around her. Separation may be difficult. Advice please.

No, the growth will actually be accelerated, as the dog will grow longer Usually sexual maturity will stop growth, If you remove the testicles, he will never become sexually mature, therefore will grow longer. Have him neutered at 6 months, if you cannot separate him from his sister when she is in heat. Or have her spayed before her first heat, also at around 6 months of age. When he starts roaming, have him neutered. Don't wait until 3 months after starting to roam.
