Wow, yes, a huge change that will take a lot of getting used to! Honestly, as someone who has lived with dogs in springfield and elsewhere, (and as an urban planner), I find the dog walking to be of relatively low quality within the city— it’s extremely car dependent with a lot of noise and poor pedestrian infrastructure. There are greenways, but they’re pretty boring in general and not practical to make a loop out of. There is a nice watershed park north of the city called Valley Water Mill which makes for a lovely little hike around a lake in woods, and as far as neighborhoods go Rountree as another person mentioned and Phelps Grove are great quiet places with good side walks.
