Moving in two shifts, approximately 150 children from Eastport Avenue Elementary School walked laps around the Claymont High School football stadium Monday.
They were hoping to raise money to help a friend, who had become a huge part of their school over the past two years.
Their friend is a 6-year-old half bloodhound, half-Labrador named Murphy.
Murphy and his twin brother, Marley, have become a fixture at the school, helping children practice reading.
Every Tuesday and Thursday, the dogs make their rounds to various classrooms and then sit in a special clubhouse in the cafeteria waiting for students to read to them.
On Easter Sunday, Murphy suffered a spinal stroke. While he has started walking again, he will need physical therapy and the cost to his owner is growing. Eastport students and their teachers have been working to raise money ever since, hosting mismatch days, and putting money in class jars and, on Monday, holding a walk-a-thon.
