The huskies Mishka and K'eyush have also been pretty popular over the last years. Videos of 10M+ upvotes, so obviously somebody's been watching. A lot are kind of painfully viewing owners poke their canines for likes, yet there are a few that are rather clear human language use such as Miska singing "Jingle Bells". Very obvious human word use and response to human communication for a task.
