10-year-old Jack Lis was at his friend’s house when he was savagely attacked by a powerful and aggressive dog. Despite desperate attempts by first responders, his injuries were catastrophic. Jack’s death was one of the first in a series of deadly dog attacks that were sweeping the UK. With over 50,000 XL Bullies in the country, their massive size, strength, and potential for aggression created a wave of fear in communities. Following newspaper campaigns and public demands for action, dog owners feared a knee-jerk reaction that would punish innocent animals. But as the list of fatalities continued to grow, action had to be taken.
