Neutering is typically performed on dogs when they are between 6 and 12 months old. However, the ideal age to neuter a dog can vary depending on the breed, size, and health status of the individual dog. It's best to consult with a veterinarian to determine the best age to neuter your dog.

In general, neutering can help reduce unwanted behaviors such as aggression and roaming, and it can also help prevent certain health problems such as testicular cancer and some prostate issues. Additionally, neutering can help reduce the overpopulation of dogs, which is a serious problem in many parts of the world.
