This seems a little unusual to me - usually 'cat flu' is caused by two different viruses that are specific to cats. A secondary bacterial infection is possible and that may have been transmitted to your puppy. She may still be recovering from her hospital stay and it is normal for a dog to be a little lethargic for a few days following discharge. If she seems very lethargic, if she isn't eating, or if she seems to be having difficulty breathing you should contact your vet.
