Neutering male Malamutes or Huskies at 6 months is a bit of a hit and miss operation as far as I'm concerned.

No matter what breed you keep there can only ever be a guide to the age of castratation as each animal is different.

I have the distinct impression that the timing of castration is less of an issue than the choice of breed to keep.

These are serious dogs with serious issues and they need serious handling, neutered or not.

Castration of any dog of the sledging breeds does not automatically mean that he has lost his balls if you know what I mean.
