So sad! Dear little Annie! My husband Tim says this happened years ago to one of their Collies in rural Nebraska :-( - a neighboring farmer poisoned the dog. Okay, if your dog wanders off, its safety is jeopardized. Our dog Mike (1970s, on our Iowa farm) used to run off and drag home corrugated steel hog pans - who ever heard of a dog who couldn't get his fill and had to bring the rest home for later? sigh That dog was hit by the school bus one icy day when he raced over to greet us coming home, his daily habit. Killed on his own turf for doing what dogs do best.
