It's pretty tuff ... trying to get a Yorkie to stop doing what they have been bred to do
and that's ..... being an alarm dog
They do have Bog Mouths for such little guys
But it soounds like your dog might be a bit insecure and that's why you barking at night when you're not there to protect her
and the crying in the car
which she likely assoc with some bad experiences
with the car
play the in and out game where you intice her into the car with some treats and
get her to assoc good things with the car
then take her to a park or somewhere she will enjoy and keep praising her for not crying
one thing is don't scold her when she does cry
you making noise.... when she crys only inforces her bad behavior
