Some Yorkie's don't like toys. I've had two like that. I have one now. He like to play with me and with our other Yorkie but shows no interest in toys. He's Angus. Trouble, our other guy, is a toy nut. If one of his many toys isn't handy he'll pull a washcloth out of the dirty clothes bin and play with it.
Both of the Yorkie's I've had who didn't like toys were master paper shredders, though. Give them a paper towel and they could cover the entire house with the pieces.
