This is not an uncommon event in dogs especially breeds like the labrador retriever. Eating a meal this quickly can put a large breed deep chested dog at risk for bloat. So, you can feed her meals in 2-3 courses. Give her a little at a time with a 5-10 minute break between each course. This will also allow for better digestion and reduce the risk or the whole meal coming right back up. I hope this helps and gives you direction.
