You may have seen the clip of the four pugs tilting their heads at the same time (they're featured prominently in our video above). Turns out those aren't the only pugs who've developed that habit.

National Geographic took a stab at explaining why pugs (and numerous other breeds) do the whole head-tilting thing, but it seems like no one's really sure. Whatever the reason, it's adorable. And thus ends our week of pug videos. Hope you've enjoyed watching them as much as we enjoyed making them!
