My Yorkie will politely tap her paw on my leg and look at me, if that doesnt work.. a low growl. Sometimes she will sit next to me on the couch, put a paw on my arm and look at me as to say "Im waiting!" SOO spoiled but atleast shes very polite
When my Yorkie wants under the covers in bed, she will scratch my shoulders trying to get under the blanket. OUUUCCCH!
I hope you dont give in to what she wants! Hopefully with time she will understand thats not how she gets her attention. Maybe try some bitterapple?
