Thanks for all the warm wishes and consolation.
I arrived safe and well last night and got a decent night's sleep after a verrrrry long journey.
It was a horrible decision to have to make, but after 10 months I just couldn't leave Diane hanging anymore.
Pip is a wonderful dog an I know that whoever does rehome him will love him just as much as I do. He will be well cared for and that's what matters.

As for me, I am just adjusting to this thing you Americans call sunshine...
