A vicious dog has been put down after sinking its teeth into a grandmother’s face as she took part in the ice bucket challenge.
Brenda Rigdon, of Florida, US, was attacked in front of her grandchildren after she took the icy soaking last year.
She has only released the video now as a warning to other dog owners.
The pit bull is seen launching at Brenda’s face and dragging her to the ground.
She’s mauled for a short while before the dog is restrained.
The victim’s son said: ‘She lived to tell the tale of it and didn’t want this released until she was ready.
