I have anecdotal first-hand experience with a dog who smelled cancer - or at least something very wrong with their health - in a loved one, and there seems to be other anecdotes, too [1]. My family member already knew she had ovarian cancer, but when we went to visit a friend's house with a dog she had never met, the dog acted in ways that the owners were amazed to see. The dog usually was a ball of energy, running all over the place, but when my family member with cancer sat down, the dog was extremely gentle and wouldn't leave her side. The owners said this was not at all typical behavior of their dog.
