Without further information it is very difficult for me to provide the best advice but I shall certainly try.
Please reply when you can and we can continue the conversation.
A reduced appetite, lethargy and diarrhoea can have many causes in a young dog including a gut obstruction, infection, toxin ingestion etc.
A vet visit is best so we can determine what is going on. The vet will examine her and may run some tests such as a blood test and abdominal scan.
Treatment will depend on what is going on and may include e.g antibiotics and intravenous fluids.
Hopefully she is on the mend very soon.
This is just Dr Linda checking in to ensure this is all OK?
