Think about the walks they repeat
The loop before breakfast, a weekend path along the coast, or the park near their first home together can all make a personal choice. Pick the place they would recognize without an explanation.
Ask without giving everything away
If you are not sure, ask which walk their dog gets most excited about. You could also ask someone who walks with them. Use a route you know, then check the streets and paths before ordering.
Keep the details personal
Add their dog’s name, a place name, or coordinates. Leave a line blank if the route already says enough. Review the spelling and layout before you choose a print or frame.
