His mother Chelsea Bromley heard the commotion and charged at the animal. The family says as she was trying to pry the animal's jaws open, she cried out to God for help.
The animal soon released its grip and took off.
Zach is recovering with gash to his head, neck and arm. Conservation officers have euthanized the animal.
