Wayland Town Crier 5/4/15: Sudbury dog shelter fundraiser attracts thousands. Save A Dog shelter held one of its most successful Paws in the Park fundraisers this year as the annual event, now in its 15th year, raised thousands of dollars to help the shelter buy its Sudbury property. Every year, thousands of visitors, both two- and four-legged, come together to enjoy a spring day and raise awareness about the importance of adopting shelter and rescue dogs.
