Ridgeback Pup Runs Very Fast To Find Ridgeback Dog She Lost

Tommy Girl forgets that Mister Brown is faster than she is so if she isn't watching when he suddenly sprints off she's left wondering where in the forest he's gone.
First thing she does is check with me to see if he's come back 'home' ('home' is where ever their people are), then she turns her nose to the wind to try to get a current reading, and yes she got him, in the bush to my left of the fire break.
