I would feel horrible because of what is actually happening. I personally don't support spaying and neutering pets, and it is becuase I believe that doing so has no benefit to the animal if housed properly and only benefits the owner. Un-necessary procedure IMO. I know that male dogs that are neutered live longer because they will escape and go chasing ladies but if you as an owner maintain the fence in the yard properly that can't happen, can it? Not telling you that you're a bad person, just why I personally would feel horrible about it.
