Black-and-white border collie mix found near Bullring

I found a medium-sized black-and-white border collie mix this afternoon around 4pm wandering near the Bullring Shopping Centre on Exchange Square, Birmingham. It wears a red nylon collar with a blue heart-shaped tag that reads 'Milo'. The dog has a small scar on its left hind leg and a white patch on its chest that forms a narrow V. He seems friendly but a little anxious, and he sticks close when I spoke to him. I know how stressful it is when a dog goes missing in the city, and I’d love to get him home to his people. If anyone recognizes him, please email me at [email protected] so we can arrange a safe meetup.
