Not really I have a BC who has always eaten just one meal a day from day one I was quite worried til he breeder told me his mother did just the same & he is her spitting image I managed to get more down him by giving him the reat as titbits during training & for "going"outside. He's a really intelligent dog he only ever pee'd once in the house when I first got him & has always asked to go out just like his mum apparantly
My cavaliers have all been picky most unusual for the breed in general but my breeders dogs aren't piggy like lots of cavaliers
You might be just giving her too much altogether so try giving her a little less split into three meals
