Many thanks for all your kind words. We're still very sad, but we know it was what had to be done. It was made harder because he didn't really show his suffering and seemed so much like our cheeky old chum right until the end. He was 13, so didn't do too bad and yes, we have great memories and know he spent his last year as close to us as any pet could be - literally, since he snored away under our bed every night and on his own seat in the van every day.
It's going to seem very quiet here now though. Last weekend we moved from Leicestershire to a new house, in a new area (Duxford), but Rob is still working in Coventry during the week, so I'll be all on my own. We will get a new dog, but in the interim I might put my name down to foster dogs for the local rescue service. They often need homes for pets if owners go in hospital or have to move house where they can't have a dog etc. That way I'll still have the dog walking and the company, but not the same emotional tie for a bit.
