Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. You need to get her wet food for large breed puppy, it may be one of the premium brands (Hill's, Royal, Eucanuba), but you can find something cheaper. If you use any of these food, you should not given any additional food supplements. Alternatively, you can cook food for the puppy. Mixture of cooked lean meat with rice, pasta and vegetables will be a good choice. In that case, you should add food supplements (from a pet shop or your vets) containing calcium and phosphorus. You can crate her if you have big enough cage.
