May 13

Yawn next to your dog, and it will likely do the same.  Though it seems simple, that contagious behavior is actually quite remarkable.  Only a few animals do it, and only dogs cross the species barrier.  Now a new study finds that dogs yawn even when they only hear the sound of humans yawning, the strongest evidence yet that canines may be able to empathize with people.
