I have 4 yorkies, 3 males and 1 female. The female is the only one who does that. Her teeth was bad so i thought it was because of her teeth and the vet said they were probably hurting her and thats why she was licking so much. She mostly licks the covers on the bed etc. I took her and got her teeth cleaned, she had a couple retained baby teeth that the vet pulled, i thought she wouldnt do anymore licking...well i was wrong, shes still doing that, i think its just a habit.
