"Some of the other speakers were Dr. Peggy Root Kustritz, who spoke on
canine reproduction:"
"Dr. Kustritz talked about diseases related to reproduction. Although
spaying and neutering have advantages, there are also dangers.
Advantages include the elimination of testicular cancer and of benign prostatic
hyperplasia.
On the negative side, males have a strong correlation to obesity after
castration, though there is no definite cause and effect. Castrated dogs have
twice the risk of developing prostatic adenocarcinoma as they age. They also
run a higher risk of developing osteosarcoma as the age. There is a
predisposition in large and giant breeds of this occurring. Neutered
Rottweilers
have a definite genetic predisposition to osteosarcoma. Acute Cranial Ligament
injury is seen in greater numbers with castrated dogs."
In bitches, spaying reduces or eliminates the risk of mammary cancer and
pyometra. However, it also increases the risk of osteosarcoma and
transitional cell carcinoma. It also causes incontinence in up to 20 percent of
females. Spaying before three months of age increases the risk of
incontinence.....There is a strong hormonal relationship between
spaying/neutering and the
diseases specific to each."

These were comments, if you notice, but a 'canine reproduction' vet -- the only comments I have heard like these have been from repro vets whose livelyhood stems from dogs breeding and producing puppies so you might want to consider that their vested interest involves things best associated with unaltered dogs.
All those informations are true. You have to consider the breed, the age, the sex and the lifestyle of each individual before you make this irreversible decision:
