If she's full of energy, then I wouldn't worry, she's obviously getting enough for her requirements. Do you think she's thin, I mean too thin? I hate to see a fat dog, so to me a dog that you can feel easily but not see ribs sticking out is about right, they should have a waist. I bet she's fine, and anyway at her age you don't want her carrying extra weight on fragile baby joints. Never go by what it says on the dog food bag, it's always too much.
