Amanda Bynes -- My Puppy Dog is DEAD

Horrible, terrible, tragic, heartbreaking news about Amanda Bynes missing 4-month-old Pomeranian Little Angel ... she's no longer with the living.



Bynes tweeted the gloomy news moments ago, saying, "Sad day....Little Angel is in heaven now. RIP I love you."

This morning, Bynes announced Little Angel went missing sometime yesterday -- and begged her Twitter followers to help her locate the young pup.

So sad.
