Baxter is a full-grown long-haired chihuahua who likes howling along to Vampire Weekend's 2008 hit song "Cape Cod Kwassa Kwassa." Baxter's owner, Geoff Stockton, says he discovered the pooch "has a serious passion for singing" a few months before posting the video. "High pitched vocals and/or harmonica provide all the inspiration he needs," Geoff writes. Baxter was unavailable for comment.
