I've had 4 Rottweilers and numerous foster dogs and all of them ate like it was their last meal...if they did not I would be worried.
Sounds like your girl has a good appetite and likes her food. Try adding a bit of warm water to the kibble...it may get her to slow down a little bit...or put some of her kibble stuffed into a Kong, so she has to work at it a bit to eat.
Use her love of food to your advantage...training should be a breeze with food rewards.
