Call me crazy but what the cons of not having a dog nutured
 

I was considering not having Sammie nutured. Where he is having the little cough thing I am afraid putting a tube down his throat is going to make his trachea worse. I don't want to do anything to make it worse. So what would be bad about not nutering him?

I don't think it will make it worse but if you are worried you should ask your vet. Not neutering can cause marking all over the house, if he smells a female in heat even a mile away he can hurt himself getting to her ( there have been many horrible story's of male dogs dying or getting very hurt trying to get to a female in heat) and run off and get lost, testicular cancer, problems with other males dogs especially if there not fixed, and sense it's very easy to tell if a male is fixed or not and sense yorkies are the top stolen breed someone could steal him and use him or sell him to a puppy mill, it also becomes partly your responsibility if he accidently mates with a female. My yorkie has slight collapsing trachea and has had 4 surgerys and never any issues. My moms yorkie has worse ct and had a dental with no problems.

First this conversation needs to be had with your vet, as well as an on line discussion forum.

Some gentle questioning of your vet along the lines of their experience with small toy dogs, the anaesthesia protocol they use. What are the nature and types of the complications that they see after surgery? How would this vet safe-guard the trachea during anaesthesia especially if your dog has CT?

For the most current anaesthesia protocol in our library here you can find an article/stickey on it.

Usually for most breeds (but not all), neutering a male is done for ease of ownership issues. That would include marking in the house certainly common for male Yorkies that are not neutered. Testicular cancer obviously can't happen if a male is neutered although the risks of this type of cancer are very low.

If you own an un-neutered male, there is an increased risk of roaming behaviour, but just as important you need to safe-guard your dog from un-intended breedings, and if this does happen you are at least morally 50% responsible for any ensuing litter, and its' associated costs.

Owning any dog is a big responsibility, only an intact dog is an even larger one.

Good luck with your decision.

I would neuter just to prevent the marking if for no other reason. Also, I personally would never take the risk of health issues or an unintentional breeding as a result of not neutering my pup.
