I have a yorkie with almost all the same proplems !
When we got him we did'nt raise him anything up at first ,he pee'd inside , barked nonstop, then i started to raise him more up , ban him things that he should be banned, AND when he stopped being naughty I tried to be the best person in the world, said ''Good boy Fido! you're so good boy!'' or something like that, now he's 2 years old and he's almost perfect
I got him when he was turning 6 months old (5 1/2) , then he was used to pee on this litle pee pads.
Take the pee pads from him, put them right up to the door at first, when he gets used to having it there then put it outside up to the door, then he see's that he is suppose to pee outside.
It's really really hard to potty train a yorkie if you still have peeing pads, its almost impossible! so put them firt right up to the door , then outside after some time, then take them at all
Fido was about 3 months getting potty trained but ofcaurse sometimes he did mistakes, most often was it my fault (I forgot to take him outside).
He didnt know how to let me know he needed to go outside , i reccomand you take him outside every 2 hours.
And dont forget to say ''good boy'' and such things, and give him treats when he does right!
thats so important!
About the barking, Fido still barks, yorkie's bark, thats really normal cause they were trained to be guard dogs in the begining and chasing rats and mice.
But you can make him bark less.
I ban Fido to bark, but i encourage him when he stops, if i have treats on me i give him one when he stops, he barks less now than he did a year ago.
Fido runs around the house alot and is very energic dog, if he doesnt get his excercise, then he's hell inside! If he gets excersise he just chills inside.
Try excersising him more, Im sure that he will be MUCH easier then, Fido doesnt even bark when he's tired after a good walk or a run.
Beeing so energit grows off him i think, Fido is very calm now inside even if i dont walk for 1-2 days.
