Keeping a dog on a chain in the back yard with a dog house use to be "what is done."
Getting every shot the vet wanted to put into your dog every year used to be "what is done."
Feeding purina dog chow used to be "what is done."
A lot of these things have changed, but somehow the neutering thing has stuck. It has been married to the word "responsible" and that should be a crime, as most of the arguments for neutering allow you to be less responsible. And there has been a lot of propaganda and misinformation about the benefits or need for neutering, while the possible disadvantages are glossed over or not mentioned at all.
Neutering your dog will not make him easier to manage.
Neutering your dog to keep him from roaming is barbaric, won't work and you will have to dish out the money for a fence anyway.
Neutering your dog so he will not have to suffer whenever there is a bitch in heat is nonsens.
Neutering your dog so he will not get testicular cancer is true. He cannot get cancer in testacles that are not there. However, testicular cancer is not a common concern in the breed, and if it should crop up, it is easy to treat by neutering your dog at that time.
Some male behaviors can be curbed by neutering early, but if you do not own an intact female or an intact male to show the pup the ropes, they may never take root. Also these behaviors, humping and marking, can be managed by training. Also neutered dogs and bitches may hump and mark as well.
Which leaves adding the the pet overpopulation problem. This to me is the absolute worse reason to neuter your dog. Perhaps there is a valid argument here for spaying your bitch, but like a herd of deer, you can take out 99% of the bucks and the does will produce the same number of fawns. If you irresponsibly leave your dog loose to nail the neighbors bitch who was irresponsibly left unattended and in heat, then your dog will likely produce progeny. If you keep him under wraps, he will not, and the next stray scraggly mutt will peform the job.
Neutering can give you peace of mind that you are not adding to the problem.
Neutering could be cheaper when getting a license.
One last thing, and that concerns dog bites. Certain propagation will provide statistics that show that un-neutered dogs are more likely to bite than their neutered counter-parts. However, the neutered dogs are owned by people who "do the responsible thing." There dogs are also much more likely to be trained and socialized. People who keep their dogs intact for performance, showing, and breeding are also likely to train and socialize their dogs and are less likely for these dogs to bite. The pond scum that have no business owning dogs, the drug dealers, and criminal wanna-be's who have dogs for their reputation, keep them chained out back and encourage them to bark and portray viscious tendencies do not neuter their dogs. They do not train or socialize their dogs either. I guess my point is the particular statistic is skewed.
