Lost dog springer spaniel type liver and tan male with a blue collar

I was driving home at about 10pm on Sunday 17th when a dog ran across Southport Road and I nearly hit it. I followed him for a while and got him in my car as I didn't want a car to hit him as he seemed a bit frantic. I drove around looking for someone but eventually ended up taking him home with me (I live in Southport), I really want to get his picture around as I'm sure he's maybe ran off and his owners are really worried! He's a spaniel type, liver and tan male with a blue collar but no information on the collar. I've contacted the Dog Warden today and who will be collecting him, not sure what to do from here except put his picture and info around.
