In extremely disturbing news, TMZ is reporting that Justin Bieber's father, Jeremy Bieber, allegedly threw a dog the two adopted together off a second-story balcony.

According to dog trainer Trevor Dvernichuk -- who was hired to train the American bulldog they named Karma -- the dog bit Justin's little brother, Jaxon, which reportedly caused Jeremy to freak out and toss Karma over a two story-balcony. Trevor claims Jeremy then told him not to bring Karma back until he was properly socialized.

Trevor says he decided to keep Karma as he is not only concerned for the dog after what allegedly happened with Jeremy, but because he and Justin have apparently not asked for Karma back. That is, until Trevor started telling people Karma was abandoned.

Trevor goes on to claim that Jeremy is now threatening to take legal action against him if the dog is not returned to them. Despite Trevor's understandable hesitation in giving the dog back, he feels he would face a lawsuit if he keeps the dog, and is hoping for compensation for taking care of Karma.
