Hi Emma,
I hope you get this message soon. I'm so very sorry to hear your news. OK, he's an old boy, but I know you want to do what's best for him throughout and keep him as comfortable as possible.
If these suggestions don't work, obviously you have to take your vet's advice - but the prognosis being what it is it's worth a try ;-)
Try making him some fresh chicken broth - if he'll drink, hopefully he will take this instead of water. Be sure to serve it warm and if necessary put it in a soup bowl you would eat from yourself and have it on your lap as if it's yours - this may tempt him. If not chicken you can use something like ham trotters or flank mutton to make him a clear soup. If you can't get hold of fresh ingredients until tomorrow - buy some tinned carrot and coriander soup, mine love it ;-)
If he'll eat any of the above, then in 24 hours mix a little very watery mashed potato into it to thicken - but still keep it thin enough to drink or lap up.
You could also try baby food - a simple one without too much texture so more for baby's first food, usually in little glass jars.
If the soup/baby food fails, offer him some *very* mashed up banana - sounds crazy but dogs usually like it and it's full of potassium etc. You could even mix that with a fruit sorbet to thin it down and if the polyp's are hurting his throat this will soothe him. Don't be tempted to do it all at once - he's obviously very frail and you don't want him to bring it up again.
Having not eaten for so long even if he does take anything it will only be a *very* small amount - his tummy will have "shrunk" so don't despair - if you can start him off taking something again (anything) it's a huge leap, so take comfort from that and don't try to overdo things if you get him started off.
I'll be praying for you - this must be very distressing for both you and your Mum. If I can think of anything else I'll be back on like a shot. Private mail me if you just want to "talk" :-(
Teri
