Hi Everyone thanks for all the advise.
First point, I would NEVER re-home him, I waited over 5yrs to get Alfie and hes one of the best things that's has ever happened to me and completes my life its just hard work LOL, theirs more chance of me re-homing the kids!!
Alfie does fit my life style as I spend 99% of my time when I'm not at work outside, walking, running, training with my daughter (she races bikes in muddy fields) and he LOVES it. I just don't like him being upset like I said in my first post, if it was down to me I would have him me 24/7.
He has loads of different toys to keep his brain working when we leave him,Kongs (we currently have 4 different ones) which he only has when we leave. I've set up a camera and the Kong does work for a time but once hes finished he starts listening for us and then starts to get upset but does settle after about 10 mins. As for him following me around its not a problem I just wondered if that's a normal cocker thing.

I know its going to be a long road to get him in a happy place but we'll get there in the end. Its nice to know that I have all you people with Advise if I need a drop of support sometimes. PS if anyone is in the Southampton Area and fancies meeting up for a walk, let me know.
Thanks
