Yorkies can be so picky sometimes. When I first got the Canidae, they weren't NUTSO about it like they are now. They kept thinking I was going to add something else to it so they just waited. Well, I waited them out and ina few hours once they realized nothing else was coming they started eating it and now they get really excited when its "feeding time"
I leave their dry food out all day long but just add the missing link or salmon oil in the mornings and evenings.
