Human yawns are also contagious to dogs

When humans yawn, is it contagious to dogs? Yes, A recent study by the University of London has suggested that the ‘contagiousness’ of yawns by a human will pass to dogs. The study observed that 21 of 29 dogs yawned when a stranger yawned in front of them, but did not yawn when the stranger only opened his mouth.
