TEACUP DOG HELP PLEASE!!?

I want to adopt either a Teacup Yorkie or a Teacup Chihuahua.
I am looking for one that I can get for free, adopt somewhere.
I want to get your opinion on which dog would be better!
I want it to be at or less than 5 lbs., FULL GROWN.
Are long or short hair Chihuahuas better?
I know how Chihuahua's can grow up and have coarse-looking (and sometimes feeling) fur & can be 'stocky' adults like these:

And Yorkies have that "grayish" hair, which is actually called "blue":

I don't order dogs over the internet, so don't give me websites to go to.

Please help me & thanks if you do help me! And thanks for reading all this too!!!!!

There is no such thing as a "teacup" for either of these breeds. There are no sub-categories for the standard based on size….just one standard. It's a marketing term used by unethical breeders used to describe ill bred runts. Reputable breeders to not purposely breed to produce extremely small dogs. If those are your requirements, I would suggest that you try your local puppy miller or back yard breeder.
If you want to be responsible and wise with your choice, then I suggest you start by researching the breeds, educating yourself on them and THEN taking the time to find a reputable breeder. It's concerning that you are willing to make a long term committment to a dog, yet you have not even bothered to educate yourself on the breed first.
