I understand about the Science Diet - all my Basenjis have hated it! We use Eukanuba Lamb and Rice or Kirkland Lamb and Rice from Costco mixed with a little warm water and a tablespoon or so of Pedigree canned. (of course, they also get a little Red Barn rolled, green beans if I'm trying to get them to lose weight, left-over bait from the dog shows… no, ours aren't spoiled either!) Only get the Pedigree canned puppy or the CHOPPED dinners (not the chunk) as those are the only ones without wheat. Lots of Basenjis are sensitive to wheat. My daughter feeds Purina One Lamb and Rice.
A plate or pie tin might work for her. Sometimes they just get notions!!! One of my girls won't eat if her dish isn't in the right place on the mat.
