Grass has appeared in some spots in my lawn. Mercedes has the bad habit of when she sees someone next door and gets all excited she eats gobs of grass, it is not a sick dog eating grass in order to vomit>>she just grabs hunks of the stuff and gobbles it down.....then later she pukes it up all over the rug or her crate. It is like nervous eating. All winter she has not threw up, but I see it coming with the green. Short of a basket muzzle( which I would hate to do) can I do?
