When is the best time to neuter a dog?

My vet said he would neuter them once they were 6 months old. Now I am being told by other people that it might be harmful for them to get neutered at such a young age (increase chance of bone cancer, hyperthrodism, etc.) and that I should wait until they are a year old. Is it really that bad if I get them neutered now? Are there in disadvantages to waiting?

Eight weeks to six months. Vets do not recommend waiting more than six months due to the elevated chances of aggressive behaviors and disease. The benefits in doing it early are reduction of preputial discharge, reduction of hernia occurrence and better prostate health; non-neutered dogs have a much higher risk of prostate problems.Those people you've been talking to shouldn't own dogs, as they are very misinformed.

8 weeks to 6 months. depends on size and vet.

There are no disadvantages, it's much more beneficial. Please read:http://www.naiaonline.org/pdfs/longtermhealtheffectsofspayneuterindogs.pdfhttp://www.caninesports.com/SpayNeuter.htmlhttp://articles.sfgate.com/2010-04-06/living/20836678_1_neutering-pets-mammary-cancer-bladder-infections
