Our 7 mo old Chewy ate 4 ear plugs!! They are the small spongy kind that are no bigger around than a pencil eraser. My older yorkie had eaten a few in the past and he just pooped them out, but never 4!! He somehow climbed onto my night stand and got ahold of them. Should I wait to see if he poops them out or take him to the vet tomorrow?? I am really worried now
