I think they're talking about the observation that dogs are often observed to spend more time at the front door of a house when their owner is about to return home. Even granting that this is an actual effect and not just confirmation bias (which is by no means certain), the fact that most people return from work on pretty regular hours makes this is an example of learned behaviour that would have done Pavlov proud. But for some reason a lot of woo-woos seem to prefer viewing it as an example of telepathy.
