Another thing to consider when talking about Yorkies is their likelihood of having liver shunt. This especially goes for those whose paretns haven't been tested or their lines aren't clear of the problem. Shunt surgery can be done at the time of spay/neuter and with the females, the abdomen wouldn't have to be opened again.

I see very few benefits to anesthetizing a 12-16 week old puppy. You can't really even bile acids test at this age and get an accurate reading. Some owners prefer to do this before any surgery is done.
