Lucy, a six-year-old pit bull from Fort Myers, Florida, will always be remembered as a heroic dog. The loyal dog defended Lisa Potts with her own life as Potts’ boyfriend hit and attacked the woman with a knife. Unfortunately, Lucy did not survive the attack.

The dog who belonged to Potts’ son was at home on Dec. 18, 2015, when a violent fight between Potts and her ex-boyfriend, Walter Williams, broke out at home.

Walter started hitting Potts and took out a knife with intentions to cause Potts serious injuries, but when Lucy saw the violence she sprang into action, defended the woman and took the majority of the blows.

“Lucy lunged at [Williams] and once she lunged at him he caught her in the neck,” Potts told Wink News.

Even though Lucy was injured, the dog kept on defending the woman.  With blood trickling down her neck, Lucy bit Walters multiple times. The bites were enough to stop Walter, but Lucy was left seriously injured.

In a state of panic and fearing for the dog’s life, Potts ran outside with the bleeding dog.

“Once I got [Lucy] downstairs I just asked someone for a towel and applied [as] much pressure [as] I could to it to try to save her life,” said Potts. “I was calling [Lucy’s] name, comforting her, rubbing her head, making sure she was still alert.”

Unfortunately, Lucy died the following day.

Police arrived and arrested Walters. He is being held on a battery charge.

Lucy might no longer be with us, but her family says they will never forget what she did for them and will always remember her as a hero.
