Nebo was neutered at 4 months. He's the only dog I've personally been responsible for and paid to have it done.

Sydney was spayed when my sister had her...she was still a pup, I'd say around 6 months or earlier.

Reggie was not neutered until after we got Nebo (and no we did not breed him or let him roam my parents just didn't understand the need to do it...they have since learned) I think that would make him about 9 years old when it was done.

My pets will always been spayed/neutered.
