Nintendogs Causes Dog Attack?

Last week a child was attacked, while playing Nintendogs, by a friend's dog.  Hearing the barking of the virtual pet seems to have caused the dog to go berserk, pulling the child off her sofa, and then biting her lip off.  Luckily, the child has been able to have her lip reattached, and the dog has been put down.  You can read the full story here.

It's somewhat shocking that a game, such as Nintendogs, cause cause such a violent outburst.  Is the fault really with the game, or could the attack just of been due to the poor judgment of leaving a child alone with a potentially dangerous animal?
