According to an article in Jewish World Review Yawning is how dogs show they love you:
Scientists think dogs might be feeling empathy for their owners when they do what humans often do with one another: contagious yawning.
Dogs yawn more frequently when the human yawner is their owner than when it’s a stranger, researchers said in a study published Wednesday in the journal PLOS One.
“Our study suggests that contagious yawning in dogs is emotionally connected in a way similar to humans,” Teresa Romero, who conducted the study with colleagues from the University of Tokyo, said in a statement.
So, go ahead and yawn. If he yawns back, he loves you. If he doesn’t, perhaps you DO bore him.
This is better than my cats who show their affection in other ways — which is why the book I Could Pee On This is “poems by cats” not “poems by dogs.”
