This is a difficult call. It's easy for me to say don't worry, but not so easy for you, she's your dog. However, if she is full of energy and happy to play, then like Tohme I'd say there isn't too much wrong. Has she lost any weight? If the vet has examined her thoroughly, and is happy, then try not to worry too much.
While she is otherwise happy and apparently healthy, I would continue to pick up her food bowl after a limited time, and not give in to the compulsion to pander to her. One thing is for sure, she most certainly will not starve herself.
Of course it goes without saying that if she becomes ill then get her back to the vet sharpish.
Why not join Champdogs, it's free, and you can let us know how things are going and we can give some support and encouragement.
All the best, Dawn R.
