i had nearly the same problem with Leika. I use Eukanuba puppy for small breeds, she didn't eat from her plate 'cause it was too big for her and it wasn't 100% her own. It belonged to my old dog Ringo. I used to give her in my hand, but you shouldn't do this, this will get you to give her everyday food from your hand. THen I bought the right plate for her. Maybe that's her problem?
