Hi, and welcome! Yes, get your puppy on a better food. Purina is full of crap, by products and fillers. Do a search, TONS of great information here on premium kibble that uses human grade meats. You can feed less of the premium stuff than what you're feeding now. Puppy should be eating 3 times per day, not two. Once in the morning, once in the afternoon (noonish) and once in the evening. Eating half of her daily rations in one sitting is too much for her tiny belly.

Also, if your puppy is on a premium food, there is no need to feed supplements at this time. The food alone should be enough.

Give her time to settle in. Puppies tend to play very hard, then just DROP to the ground.
