@Kerin thank you, it has been lovely watching him become more comfortable around us. When he first came here he was so flat and had no energy. He never really got excited, other than wagging his tail (cautiously) when you were stroking him. Now he goes mad in the morning when he see me and is so full of life. When he sees me put on my shoes and get his lead he gets very excited and runs to the door. He has also become quite verbal and 'talks,' especially if he see something he wants.
