It could be Lady is suffering from intestinal worms causing her to have diarrhea and not put on weight. They can be common in puppies. I would have her checked out by a vet today or tomorrow, and bring in a sample of her feces with you for the vet to examine under a microscope. If she does have worms, the vet can give her a deworming treatment. Best of luck, I hope this helps!
