Hi it depends if your dog is gobbling it down or just chewing on it. If your dog is chewing the grass she may just have a craving for it, if you want her to stop try giving her a bit of broccoli or other fiberous vegetable. If she is gobbling it down she may feel sick, all dogs eat grass when their tummy is upset as it makes them vomit. If this is happening take her to the vet. I have a puppy at the moment and I think she just eats grass sometimes to explore it! It's nothing to worry about though! I hope this was a little bit helpful and I'm sorry if your dog is a he because I've been saying she throughout this thing
