The most immediate reasons for neutering dogs have generally been population control and behavior modification. In the US, policies for adoption also lead to the mass use of prepubescent neutering. As an additional benefit, for female dogs early spaying greatly lessened the risk of mammary tumors, and in general spaying removed the risk of pyometra (infection of the uterus).
However, may negative health effects have also been noticed over the years. Joint disorders like hip dysplasia and CCL tears (like ACL tears in humans), cancers like mast cell tumors and hemangiosarcoma, and urinary incontinence in females have been associated with neutering. Joint disorders have been particularly associated with the age at which larger dogs were neutered.
This interesting study looked at the medical benefits and risks with different ages of neutering for different dog breeds and sexes, and it even has a nice chart of guidelines here.
