In the same Psychology Today article that talked about animals love for one another, there was a reference to their unusual ability to sense the death of their masters. The article even spoke to the fact that dogs (but never cats) often stayed by the graves of their deceased human companions, often until they, themselves, died.
One of the stories in my book is about such a instance. The story is true, and, yes, I was an early advocate of placing signs that announced the presence of steel traps. I hope you enjoy reading, "A Dog's Sixth Sense."
