I have heard that you should neuter your dog because if you don't it can lead to cancer also if you don't spay. What are the chances? How many people here have there dog spayed or neutered? My 11 month old puppy isn't neutered yet but I think I am going to because of his intent to wander over to the neighbors. My parents dog did that and they had him neutered and that stopped him. Since I don't own the land where my house is I can't put up a fence (wood, metal, electric or otherwise.) He is a farm dog that is being trained to herd cattle. Will neutering him stop his wandering? He is now tied up during the day since my husband and I work. My parents check in on him.
