Buddy is in a foster home with a view to adoption

Buddy was found wandering down a road in Surrey, he is very thin and a bit dirty.  The finder reported him to the dog warden but kept him in her home as the pound was completely full.  She cannot look after him as she works full time, apparently she was told that his time would be up on Sunday 15/01/12 and because the pound was full and she returned him he was likely to be pts. 
Buddy is a friendly dog, a little scared when he first meets you but soon comes around.  He is not housetrained although he was getting better in the home. He could have previously lived outside as his coat is quite dirty , he only weighs 24kg.  He is in boarding kennels at the moment, but if anyone can offer him either a permanent home or a foster home so we can get him built up please contact me. Buddy is around 1 year old.
