I'd wait until at least 6 months. I don't know whether it's true in dogs, but in cats, if you neuter males too early, the urethra will stop growing in diameter and they won't be able to pass stones as easily. When I had a cat with bladder stones, that's what the vet said, and he required catheterization. All in all, I think it's best for dogs to finish their growth and development before they're neutered. |
