One of my dogs ears grass and makes herself sick about once a week. Vets suggested changing food ,giving a snack at night etc. Did this but no change. Since starting adding this to their food she hasn't done it,that's about 10 days now,so I'm hopeful that that will remain the case. In addition to which both of them LOVE it. It actually makes me laugh out loud to hear them licking their bowls so thoroughly and then their lips and whiskers. Not a crumb goes to waste!!
