The Male I had that was cut had more drive than any dog I ever hunted over.
He'd hit geese like a linebacker with a free shot at a quarterback, after he was cut. His drive was controlable.
His blood line was good and I thought about breeding him, but when his testosterone kicked in, he got mean.
Wanted to kill, not just rough up all other male dogs. It was either cut him or put him down if cutting him did not reslove the issue.
I will not have a mean dog around no matter how good it is.
Fortunately, it did work and he became a great hunting dog without the dominance issues.
After a month or so (takes that long for the hormones to purge from their system) he no longer wanted to fight and he no longer spent half a hunt with his nose up a FM's back side.
Unless you have genetics and a plan to breed, and do it right, save yourself a lot of potential trouble and have your male cut.
I do leave them intact till they reach their full size to help provide complete joint developement.
