My friend cited a study by Rupert Sheldrake which ran an experiment over several years that video taped dogs, showing that dogs knew when their owner was coming home due to some psychic link. He published a paper called: A Dog That Seems to Know When His Owner Is Coming Home: Videotaped Experiments and Observations.

He seem to be a frequently well references researcher, looking over Google scholar. He even published a book about the results.

Has this been independently verified, do animals have telepathic links with their owners?
