A two-time mauler is a pit bull that has mauled two human beings. A two-time mauler does not indicate “two bites”; it indicates two serious attacks resulting in serious injury. The instance of Matthew Havern and his two-time mauler named Graham perfectly fit this definition.

Alorah’s mother, Julie Havern, said her daughter suffered a fractured skull and required more than 300 stitches to close her wounds. She also lost many teeth and had many bones in her face shattered.
In November 2006, this same dog attacked the 4-year old daughter of Matthew’s girlfriend. Her injuries included: partial loss of sight in one eye, a broken jaw and the loss of many teeth. – Kara Murphy, GoErie.com
