Oh, how I hate June bugs!!! We get them in May though. I've never noticed my dogs eating them thought. But then again, I try not to go out at night because I want to avoid June bugs. My one dog, Patience, tries to eat the bumble bees that fly around though. I always tell her not to. I explain to her that she doesn't know how much that is going to hurt. I figure that once she finally catches one and it stings her, that she won't do it again. Sorry, I have no suggestions for you either. The only thing I can say is try not to let them out that much after the bugs come out.
