You can go to this website to see info on how your dog should look and how to determine if her weight is ok.
What we have always gone by is that if you place your hand lightly on their ribcage, you should be able to feel the ribs if you press lightly. If you cannot feel them, she is too heavy. If you can feel them without pressing at all, she could probably use a few pounds.
