Alan m8 i do feel for you as you do get very much attached to your mans best friend as i had a dog myself and i know when you lose such a friend but anyway he could of strayed into the housing estate there and i would check it out with the police there as you never know your luck someone could of handed him in there or someone may have him in there house not knowing where he/s from and with him being blind he cant show where he is from or where he came from so if you check with the police first they might put you onto any dog kennels there who might have him so good luck and i do hope you find him.
James it's not my dog, just passing the word around, it belongs to a member of the Northern Engalnd Springer Spaniel rescue (I am a member) everything possible is being done to find him, doglost.com is co ordinating efforts.
