Since your puppy feels well and is playing you can allow her to decide when she is hungry. I would let her go 3 hours or so without forcing food and just make a selection of food types (baby food, chicken, kibble) and you might try scrambled egg or a different type of canned food. I find a lot of puppies like Iams canned puppy food. Sometimes a light sprinkle of garlic powder enhances appeal. There is also a frozen food called Bil-Jac that is also enticing. You can also reduce the amount and frequency of Karo, go with 1cc Karo and 1cc water each 3 hours if she feels good. Please keep me innformed through INSTAVET or the forum or chat.
