Your baby is very tiny and perhaps does not need so much food?
Some dogs are also very picky and changing food many times seems to make them worse! They hang out for the 'good stuff' and won't eat the regular food or kibble.
Are you sure your pup does not have any teeth or health issues that are making her not want to eat?
If she is healthy then perhaps the kibble size is too big? You could break it up into smaller pieces and add some tasty topper mixed in so she cannot pick it out. You could also try adding some liquid to soften the kibble. Not so easy to pick out good bits from wet kibble!!
I know my dog, who loves his food, picks out the kibble and throws it on the floor at first, eats the chicken bits and then eats the kibble he put on the floor!
These dogs have weird eating habits sometimes! Good luck.
