I thought that's what our Yorkie was eating since when I get to her I can never find anything. We have tons of squirrels in our neighborhood, especially since the woman across the street feeds them. Everyone else in the neighborhood would like them to thin out or go away. I will try the vinegar once the yard is in better shape. We have two things back there now, snow and mud. UGH!
