Miley Cyrus' dog Floyd died right before her Boston show, and the pop star was seriously distraught by the news. Instead of her playful set, Miley took the tone down a notch and played an acoustic set for her fans, dedicating Fleetwood Mac's "Landslide" to Floyd. 

An unearthed video shows Miley addressing the crowd, telling them that the classic tune was Floyd's favorite song, while choking back tears. Check out the emotional video in the above slide.
