My girl is obsessed with eating weeds and grass, and I don't know how to make her stop. I will try to play fetch, and she will go to the ball but then eat some grass/weeds and forget about the ball. She has been eating so much that she throws up. Last night it was the worst it has ever been. As soon as she would throw up she would go right to the grass and eat which then would make her throw up again. She was almost panicking that we wouldn't let her ourside because we knew she just wanted the grass, and wouldn't go to the bathroom. She rings the bell to go outside, but just does it to eat stuff! What can I do to make her stop eating so much?
