LOL I said the samething when I got Buddy at 14 1/2 wks.
Lucky me he does not bark! Right, give him another month or two.
When he finds out he can you will be training him not too
Yorkies are not impossible to train. Buddy was trained by 5-5 1/2 mos
and has never had an accident. He is 4yrs old now.
I crate trained him. It took persistence but in a month he was completely
house broken.
Good luck,
