I have 5 yorkies and three I got at 8 weeks and two were ones from my litters. I can say they were all easy to train when you are consistent.
My first Yorkie was very easy to train and learned sit, stay, leave it, come, down by 6 months.
The two I had from birth never were caged and were potty trained by example from the other dogs. They were pad trained by 10 weeks with few accidents. As for sit and stay they learned by example from the others in the pack.
Yorkies are very smart.
My male was the hardest to train and he finally learned everything by 1 year EXCEPT 'go home' which means go to their pen. He hates it and actually crawls around like he can no longer walk, it is too funny!
He need to be carried every time. We think it is just plain stuborness on his part.
