Tell me your postcode and what your dog finds hard, and the map shows which paths are likely to be calmer, and the best places to park and start.
Every footpath, bridleway and track is checked for the things that most often unsettle a nervous dog: how close it is to housing, car parks, parks and popular spots (other dogs and people), fields likely to hold sheep or cattle, cycle routes, shooting grounds and crops where bird scarers are used, and main roads. Your answers above decide how much each one counts, so the same map works for a dog who hates bikes and one who hates bangs.
A good walk for a nervous dog also needs sight lines, room to step aside and somewhere to turn back to. The map can't judge those, so read my walk notes too, and why decompression walks work.
