At what age do you prefer a dog to be altered?

I've been researching alot about this. I'm leaning towards getting him (my future pup ) neutered early.

I've already called some vets around the area, and the one vet that seems to be wonderful and that I'm sure to settle on neuters pups at atleast 8 weeks as long as the testicles are distended.

I've read that since vets have been spaying and neutering before 6 months like they usually did before, there has been a decrease in the amount of cancer victim dogs.

Also, the testostrone closes the growth plates, and if you neuter early, the plates will stay open longer and your pup will become longer in the legs. And I love tall dogs.


But what I'm worried about is putting a puppy through anesthesia. What are the chances of problems arising from this? Should I wait the average 6 months, or go ahead and neuter as soon as the testicles are distended? (usually can be as early as two months) What did you do?

Thanks in advance!
