Dogs Really Do Know Their Owners

Yes, your dog really does know you, even your photograph. A new experiment measured dogs’ eye movements as they looked at pictures of both humans and other dogs. Published in the journal Animal Cognition, trained dogs to look at images presented on a computer screen.
The dogs were shown pictures of their owner, pictures of other dogs they knew, and unknown humans and dogs. Researchers tracked the dogs’ eye movements and found:

1. dogs were most interested in the faces of other dogs (they looked at these pictures longest).

2. dogs spent more time looking at the faces of their human owners than they did at the faces of strangers.
