Lmao! Yeah it is pretty gross, but sometimes I think some of us forgot our yorkies are DOGS! That's right your (and my) little precious do belong to the canine family and well sometimes dogs eat poop. Growing up as a kid we had some dogs that thought the cats litter box was a doggie buffet

. Of course we did try to stop them but well... it's a dogs life.
Abi's momI'm not saying this is you so please don't take offence and I understand your concern. BUT.. some yorkie and other toy owners sometimes forget that what they have is a dog and not a barbie dress up kit

Especially true to the yorkie as it is a terrier. Sometimes I wish they would take the yorkie out of the toy group and put it with the other terriers where it belongs. Yorkies are just smaller than other terriers and that's the ONLY difference.
Sorry to go off on a tad of a rant Abi's mom nad I hope someone here gives you some good advice. Heh, my sisters yorkie does it to!
