WELCOME TO YT!!! 
you have def. come to the right place to do some research .
I think yorkies are the sweetest dogs, they are very intelligent, independent but at the same time require alot of human attention. These dogs thrive indoors with their owners. Grooming and teeth brushing is the biggest resposibility. Potty training may be a little stressful

because

can be stubborn.

But if all of this doesn't seem like too much then a yorkie baby will make a wonderful additional to your home.
