Well the main thing is that the dog/cat won't be able to reproduce. I've heard many things about neutering your pet. The one that interests me the most was that supposedly it will reduce the chance of your dog/cat running away. Dogs often run away because they are looking for a "bitch" (female dog) to mate with. Therefore neutering him will make him not want to find a mating partner. (To simplify it; the dog wouldn't be horny and wouldn't go look for a female dog to have sex with.)
Yes it does.

It's laser surgery for neutering a male dog.
It is when you sterilize a male dog.
It means the dog can't reproduce.
This is a common myth made up by Breed Registries to try and put people off neutering. Neutering does not harm the dog, but it does prevent testicular cancer and hyper-sexual behaviour.

No.
go visit your local shelter....YES!
Neutering very commonly "calms a dog down", but there are no guarantees in that, of course.
Neutering or spaying a dog does eventually make them less aggressive, yes, when their body stops producing too much testosterone. Neutered or spayed animals also have a longer life expectancy.
It depends where you live and the size of the dog but usually between £100 and £150.
No, because this would mean that the dog would still be able to sire young.
Then something has obviously gone wrong with the neutering.
