His hormones started to rage??? At eight months??? You mean he became a teenager? So you neutered him?
Did it work?
Everyone I talk to that neuters because of behavioral issues is disappointed, but that doesn't mean it doesn't work ever.
Ok, calming down now, we usually do encourage a neuter for serious behavioral issues, but that is more because the dog is not a good representative of the breed and should not be used for breeding. When you have an intact dog, even if it is not a good breeding prospect, when someone offers you a stud fee, the temptation is not there to go ahead and breed him anyway.
Bad temperament is one of the only reasons I might neuter or spay. I can keep my lot separated, but if I die and someone else gets the dog/bitch, and they go ahead and breed it, it is the only thing that pretty much guarantees the puppies a doubtful life. Health problems will be tolerated, not performing well in conformation or performance will not necessarily land a dog in a shelter. And even if it does, the dog will still be adoptable. Poor temperament is a liability not only for the owners, but for the breed itself.
If I neutered my dog, what would I have left to threaten him with when he is a pookey????
