uk yorkie lover,
I have the same problem. Gucci takes Evie's (my daugther) toys and shoes to hide them. Evelyn have to run after her to get them back. I always end up telling Gucci to "drop it", for her to let go the toys. She used to bite my daugther's feet not hard of course, but she has calm down. I also notice that if i repremend my daugther Gucci's bark at her. They adore each other, when Evie is sleeping Gucci lays next to her. Also Gucci takes her toys close by Evie to play. Yorkies can be very funny. Gucci is the Baby of the house. Everyone spoils her.
