The dog was not found by police and it is hoped its owner found it.
PC Tom Van Der Wee said on Twitter this morning: "Good morning #Twitter! I’ve headed straight out this morning to a report of a dog loose near the #A27 at #Poling.
"It was no trace so I’m hoping his/her owner retrieved them I’m back at the Police Station now to catch up on paperwork before heading out! #RPU #SussexPolice"
