God bless you for taking these sweet little creatures into your home and giving them care, love and stability in their lives. How sad that these little "oldsters" had to make a home change - but thankfully you've got them.
The little girl could be still traumatized from changing her latest home yet again and losing her former owner/caregiver and is missing her still and an upset dog is usually a dog who won't eat anything or eats only something easy to take in. Poor little babies - many homes and it sounds like perhaps little dental care but at least those awful teeth are out now and no longer causing them problems. Maybe if you tried mixing the baby food with some canned food you cooked for a few minutes in the microwave and got the odors stirred up within the kitchen, cooled it and then held it out for her to sniff and then withdraw it a couple of time to maybe get her nose and competitive nature stirred up and involved and interested, then, if she shows interest in the food, hand-feed tiny bits to her, it will get her started eating.
