Dogs walked off-leash cause 20% more disturbance to protected lowland heaths, UK study finds

Researchers at Royal Holloway University of London have used GPS trackers to measure where dogs roamed during walks in lowland heaths in South-East England, home to several protected birds like the European nightjar and Dartford Warbler. They found that 85% of the 185 dogs tracked were walked off leash, despite signs requesting dogs be kept on a leash during the bird breeding season.
