Thanks for all your suggestions, I have tried the turn and walk in opposite direction and he seems to be improving slightly i guess only time will tell.
I know I am probably being stupid whats what's a 'gentle leader', is it a type of harness that fits over his nose? I saw something similar in Pets at Home but am not sure if thats what's meant.
I actually managed to tire him out today after a two hours walk across fields and footpaths, though being tired only lasted about 1 hour before he was up to mischief again. Aren't springers great
Thanks for all your help and I will persist.
