WELCOME!
Yorkie puppies are mostly black with some tan bits. As they age they change color.
8 weeks is too young to be definitely potty trained. Generally you just need to be consistent, but you can't expect an immature bladder/sphincter to be able to control itself. Be patient and give it some more time and maturity.
I'm sure others will have suggestions for you once they see your post.
We love pictures!
