We had a retriever who walked up to a possum who was ambling by. The possum “played possum” and our dog took a sniff at it and thought “Well, this is no fun.” and walked away. So it DOES work.
Also I’ve read that possums give off an odor like rotting meat when they do this.
We still have a resident possum. We keep her around because she eats all kinds of insects we don’t like.
