Sorry to hear that Dave.
My dog died just over a year ago, had been with me 14 years, since I was around 11, fucking awful
One thing that DID make me feel a bit better was what my old man did, I phoned him to tell him and that I didnt know what to do (He could tell I was in a right state) so he told me to bring him round to his ASAP, by the time I got there in about 15 minutes or so, my old man who is getting on a bit now, had dug the BIGGEST whole right in the middle of the garden, turf up the lot, all this with an arthritic shoulder and in late november with snow on the ground

was gob smacked, in fact that gesture alone started me off bawling again
Big up to family and friends in these situations
