At What Age Should You Have Your Puppy Neutered?

The question of when to neuter your male puppy is an important decision, but you can make that determination with the help of your veterinarian and other expert insight.

  1. Function

    • To neuter means to remove the testicles, a procedure that is usually performed under general anesthesia. Neutering removes the dog's ability to impregnate a female dog, and also decreases the level of testosterone and its particular influences.

    Expert Insight

    • The American Society for the Prevention of Cruelty to Animals (ASPCA) suggests that the traditional age for neutering is six to nine months. However, if healthy, puppies as young as eight weeks old can also undergo the procedure.

    Benefits

    • Neutering removes the potential for testicular cancer and reduces the potential for medical issues such as an enlarged prostate. The reduced level of testosterone may also diminish aggressive or sexually related behaviors such as mounting or roaming for females in heat.

    Considerations

    • Neutering can increase the potential for medical issues such as weight gain, which can be prevented by proper diet and exercise. Neutering may also slightly increase the risk of certain diseases, such as bone cancers or hip dysplasia, particularly in breeds that are already predisposed.

    Warning

    • Some hormonally related behaviors, such as mounting or territorial marking with urine, may not be affected by neutering. This may indicate other behavioral issues. Consult your veterinarian if concerned.
