Again, thank you all. The keyboard was not co-operating before. A couple of red wines have helped me to relax. I've just rung the hospital and he is comfortable. Specialist will see him again tomorrow morning and make the decision on whether to do an angioplasty a.s.a.p. or let me bring him home for a few days and arrange things. It is all complicated by the fact we are still struggling with dressings for a recent tumour removal (graft is not taking).
As OP - people have been wonderful. The dog is being walked for me by 2 families, another one has taken a shopping list. I hope that this is not just normal in Yorkshire and that the rest of the UK bonds like this in an emergency.
Again, thank you all. xxx
