What happens if you neuter a Golden Retriever?

Neutering a Golden Retriever has many benefits: it avoids heat-related roaming, irritability, fighting and barking, and lowers risks of pyometra, ovarian cysts, false pregnancy, testicular cancer and prostate disease. But after neutering metabolism slows, so overfeeding causes obesity and raises diabetes, heart and joint disease; adjust diet and exercise. Also, it may become calmer or, conversely, more active.
