It only halted once Ashley came.
Ashley works with Wonder for Satos Salvage and constantly protects homeless canines (and some of the time-lost felines). She is accustomed to answering salvage calls and perceiving the signs when creatures are in trouble.
When Ashley saw the canine in the city, she realized she expected to stop.
Ashley escaped the vehicle and saw the canine was a nursing mother. Where could her young doggies have been?
