As long as you're following directions on the bag, then your baby should be just fine
If she's extremely active, she may need a little more, but it sounds like you're doing a good job.
Miko is a very picky eater, and when he was a pup, I worried if he was eating enough. Here's a tip...Measure out how much your doggie is supposed to have and put it in his food bowl in the morning. If he has leftovers by the next morning, measure and find out how much he didn't eat. If he finishes it, you know he's eating enough. Good luck!
