Sometimes a walk around the park is not enough to put a smile on your dog’s face. When Matt Buckmaster brought his Italian greyhound Penelope to the K9 Fun Zone in Seattle to meet some friends’ dogs, the animals had immense fun chasing each other through a play tunnel. The video of their game, first posted to Facebook, has picked up over 1.5 million views since being uploaded on April 28. Credit: YouTube/Matt Buckmaster
