My 3-month GSD puppy won't eat and is losing weight. What's wrong?

Pet's info: Dog | German Shepherd | Female | unspayed | 24 lbs

Hello and thanks for your great application and professional team . My daughter 3-month GSD doesn't like to eat anything and refuse the food while she was eating a lot of food and supplements and cans. She's been recently indifferent to food and losing weight ( nearly 6 lb during a week ) . What's the most important reason in your point of view? Which brand of dry food or supplement or medicine you suggest? Thanks a Ton indeed

Sudden loss of appetite and weight loss in a puppy is very concerning and may be related to fever, infection or a bowel obstruction, particularly if accompanied with nausea or vomiting Please have her assessed urgently by a vet, reduced appetite is never normal in a growing pup
