What is the best age to neuter a dog?

The best time to neuter a dog is generally around 6 months of age or when the dog reaches puberty. However, dogs can be neutered as early as 8 weeks of age. Dogs should be in good health and at a healthy weight before neutering.

Neutering a dog when it is young has a number of benefits, such as decreasing aggression and sexual behavior, as well as reducing territorial marking. Neutering also decreases the chance of testicular cancer in dogs. While it is generally recommended to neuter dogs when they are young, senior dogs can also benefit from being neutered because neutering decreases enlarged prostates.
