Step 1 : Introduction to the question "How do prairie dogs say hello when greeting each other?"
Prairie dogs are actually members of the squirrel family, making them not actually dogs at all. It is their dog-like barks that earned them the descriptive name "dogs." Their normal habitat is the prairie, thus their first name. Prairie dogs are social creatures and will greet each other by touching their teeth together in what looks like a kiss. What they're actually doing is determining whether the prairie dog they are greeting is a member of their own social group. Source: Curiosity.com
