Have Stella examined by your veterinarian to diagnose any underlying medical conditions for her lack of weight gain. Submit a stool sample to diagnose intestinal parasites, bacterial overgrowth or malabsorption/maldigestion conditions. Feed a good quality canned or dry large breed puppy food. Stop hand feeding her. Dogs thrive on routine, so begin a consistent schedule for feeding. Prepare her food and leave it down for 20 minutes before picking it up whether she has eaten or not. Repeat this at the next mealtime. Be firm and be consistent. She will not starve. She will eat when she gets hungry. You can mix in a bit of warm water or a teaspoon of plain baby food to stimulate the appetite.

    I suggest you buy a complete puppy food for medium sized dogs from a better dogfood company. I like to feed Hill's, Iams, Royal Canin or Purina as these are scientifically tested. You may want to worm her anyway, as by the time there are worms in her poop, she would be severely infected with worms. Normally you would not see worms in poop, even if the dog has worms. If your puppy still does not gain weight when eating the above food, then you should have Tassie examined by your veterinarian, as there may be a metabolic or intestinal condition that prevents your puppy from gaining weight or thriving.
