Community running event organiser Parkrun has changed the rules for people who want to take part with their dogs - banning a specific type of lead and harness.
Parkrun is a collection of 5-kilometre events for walkers, runners and volunteers that take place every Saturday morning at more than 2,000 locations.
Some of those taking part in the communal exercise events like to do so with their dogs, and some wear a harness designed for dog running.
