well a quick way to tell if she has low blood sugar is to look at her gums is they are pale...get food in her...if they look greyish white Kayros or nutrical immediately.
what is her Weight? I give diggy anything he will eat. Scrambled eggs, rice and chicken, hamburger and rice, fruits, yo-baby yogurt, basically anything you find in the toddler section is good for yorkie babis....they have dried fruits I give a lot. cheerios, chicken stix (look like hot dogs) mix a 1/2 jar of 1st food baby veggies or meats in with kibble. Diggy prefers sweet potatoes, and green beans. Just do what you have to do to get healthy food in their bellies...as they grow and get older they seem to regulate themselves better and eat when they are hungry. (we hope) lol
