Doesn't matter whatsoever! I mean.. thats just my opinioin especially if you do not plan to breed. You plan to spay or neuter right?
I guess one way that it might be important is so you can be sure your yorkie is FULL yorkie.. you're able to see the yorkies family lines.
I'm sure you'll get lots of replies. Welcome to YT! Good luck finding your first yorkie baby.
