Gelada

Friends and family members trigger more contagious yawns than acquaintances or strangers.

Gelada baboons display contagious yawning between grooming partners, those individuals with whom they have the closest social relationships.

Domestic dogs catch yawns from their owners.

Multiple studies have confirmed this, and one particularly interesting finding is that dogs yawn more in response to their owner's yawns than in response to a stranger's yawns.
