A leisurely stroll in the countryside is always a pleasure for dog walkers. But after leaving the familiar local routes there are always the worries of suddenly finding a field full of sheep, or a busy road, not to mention the difficulty of knowing which pubs and cafes will welcome dogs. Here is a collection of 20 tried and tested circular walks with plenty of opportunities for dogs to roam safely off lead. The routes vary in length from 2 to 6 miles and provide a great introduction for dogs and their owners to the superb landscape of West Sussex; exploring the high chalk grasslands of the South Downs; ancient woodland in the Low Weald; and scenic routes by the Ardingly Reservoir. There are plenty of opportunities for dogs to roam safely off lead in St Leonard's Forest, Houghton Forest or Hammonds Wood. Or for dogs who love water there are bracing walks by the coast, along the river Adur and the Wey and Arun Canal.
