Issues with an Amputated Toe in a Dog

For many years, conventional wisdom held that all dogs should be neutered at six months of age, though newer research suggests waiting longer may benefit some dogs.

Waiting until 12-18 months may help prevent joint injuries and some cancers, like testicular cancer and osteosarcoma, since early neutering can interfere with normal bone and muscle development.

Smaller breeds under 40 pounds are generally recommended for neutering or spaying between 6-12 months of age, since they tend to suffer fewer orthopedic issues.

Larger breeds should generally wait longer — 9-18 months for neutering, or 6-9 months or later for spaying — to allow more time to grow and mature.

This is often done in shelter settings to prevent unwanted litters, though it's not always in the puppy's best health interest.

No — the best timing varies by individual dog, depending on breed, projected size, health concerns, and lifestyle, so it's important to discuss the decision with a veterinarian.
