Thank you everyone! I will try all the advice and I am patient with her...I realize she's just a baby, which is why I don't want to stress her out with commands and stuff...but I'm worried about her adult behavior too!
She ate a little bit tonight (in Greece it's night-time right now), about 40 dry kibble "bits"...I hope she starts eating more! Her vet said not to worry yet...I hope she's right!
Anyway, thank you for everything! I'm so happy I joined this site! Very very helpful for worried Yorkie parents
