This is one of the things that I miss about England. There may be leash laws in cities, but in the country you don't have to have your dog on a leash unless of course you can't control it or it has aggression issues. So we could drive about 10 minutes from where we lived out into the countryside to Hatfield Forest and just let them off the leash. They used to just run in big circles around us as we walked for miles seeing nobody ............ really miss that!
