A couple's first dance is a big highlight of any wedding, but that's not the dance guests will remember most about this one. In a video that's gone viral on TikTok, the groom picked up his best girl, Rosy -- his yellow Labrador -- and the pair danced to ABBA's "Dancing Queen." The clip has been viewed 250,000 times and a lot of people are saying they're going to want to dance with their dog at their own weddings. According to a survey, two-thirds of dog owners said they'd want their dog at their wedding. In fact, 60% of people said they've already been to a wedding attended by a dog.
