I was just cruising the internet, specifically youtube.com and did a search for dancing dogs. This is what I pulled up. While watching this video you'll be smitten with the dancing couple's relationship. They are an amazing pair.
And then when you watch this video, first off, be prepared, this is a tribute and a real tear jerker. But rest assured Rookie is not passed over. I did a Google search and found that he is 13 1/2 years old and retired.
