Yes I think I will neuter him, as much as I would love a baby from him I don't think I would be able to take him to work with me. I had a male chihuahua who was an adult he was bred before and I needed to re home him because he would mark the groceries, the clean clothe etc. when do you guys think I should neuter him? Do you think at 5 months or 6 months is too soon or it's good because I avoid the bad habits. He's about 3lbs. Thank you guys so much!! I had no one else who had experience in this!!
